Why do Puppies Need Deworming?

Master of sciences, B.V.Sc. & A.H.
Veterinarian, Salem
Intestinal parasites such as roundworms, hookworms, tapeworms, and whip-worms are common among young puppies and kittens. All puppies should be given a dewormer for easily-prevented illness caused by these parasites. Read more about how to prevent parasites in your dog or cat

Common intestinal parasites in dogs and cats

You've probably heard the names before

1. Roundworms, 2. Hookworms, 3. Whip-worms and 4. Tapeworms. These are the intestinal parasites most often seen in pets, and each of them can harm your dog or cat in unique ways.

Symptoms of intestinal parasites in pets
While worms are usually found in puppies and kittens, infection can occur in dogs and cats of all ages. Signs of an intestinal parasite infection can include:
Diarrhoea
Vomiting
Weight loss
Swollen stomach
Anemia
Death (in severe infestations)

Note that these signs can also be associated with other diseases so if you observe any of them, you should take your pet in to see your veterinarian for an examination. Diagnosing an intestinal parasite infection is usually done through a laboratory analysis of your pet’s faeces.
De-worming has become a controversial subject.
Developing de-worming strategies requires consideration of a several different things, including:
• What parasites are in the area?
• Are the risks the same all year round or are they seasonal?
• What parasites pose a risk to an individual pet or what are the pet’s chances of exposure? (e.g. Does the pet go outside? Is it exposed to many other animals? Are there multiple pets in the household?)
• Are there any people in the household at particular risk for parasitic infections? (e.g. young children, people with developmental disorders that might be more likely to be exposed to pet faeces?)
Everyone agrees puppies and kittens need more aggressive de-worming, but there are a few different approaches to managing de-worming in adult animals.
So as far as myself consider regular de-worming in these schedules:
STAGE ONE
Puppy de-worming: (age 40 days – 120 days) preferably suspension
(I don’t recommend de-worming puppies before 30 days as it may affect their nutritional absorption mechanism and reduce the immunity level, while they are feeding with the dam I think they are well protected. )
1. Puppy at the age of 40-60 days while doing the primary vaccine
2. Next second dose at the booster stage around 15 days from the first dose i.e. around 55 days – 75 days.
3. Third dose is at 90-120 days
STAGE TWO
Puppies at 120-180 Days of age: preferably tablet
De-worming around 180 days is preferable and do consult with your vets for specific drug of choice depending up on breed and their nature of infection they have
STAGE THREE:
Semi adult dogs 180 – 360 days: preferably tablets
In this period you can de-worm the puppy either once in 2 months if you have a group or pack of dogs or you can once in three months if you have just one dog with you
STAGE FOUR:
Adult dogs anything above 360 days
Once in every 3 months i.e.. yearly four times is the recommended Schedule for Asia
BITCH IN HEAT: special condition
Should be de-wormed at 4- 5 th day of heat and repeat dosage at 9-10th day second dose and third and final dose is after whelping and after the milking period stops i.e. after whelping 60 days apart best way to maintain the breeding bitch as per standards
Choosing the right dewormer for your dog
There are many different types and brands of de-wormers on the MARKET: and determining which dewormer to use, whether to administer it by pill or liquid, and at what dose can depend on a lot of factors.
Knowing which dewormer to use and at what dose can depend on a variety of things such as the type of intestinal parasite present, and the age, size and current health of your pet. Aside from reading the labels on de-worming products, it’s important to discuss the options and your dog’s unique needs with your veterinarian first.
Your veterinarian can recommend a product that’s appropriate for your pet after a diagnosis has been made of the type and species of the parasite. In addition, some medications can also be used to help control intestinal parasites. Considering that some parasites can infect people as well as pets, certain de-wormers may be used as a preventive measure to decrease the risk to humans.

Hello doctor my dog, 2yr old male great dane vomits the food particularly at night. Around 6 hours after having the food which is mainly 3 egg with rice and vegetables - home made food. The food is as it is, undigested this happened twice continuously at night now. And happens once or twice a month (anytime, no time relevance) what should be done. What is better food for him, something we can prepare at home? is it something to do with rice or egg yellow?

MVSc, BVSc
Veterinarian,
Great dane is a giant breed, and needs optimal proteins to maintain his health. The food he's currently being offered doesn't appear to fulfill his requirements. You can explore to offer him 650-750gms of boiled boneless chicken + 150gms of overcooked rice in a day. About 4 boiled egg whites can be given as well. Please avoid egg yellow. Alternatively - you can explore offering him giant breed pet food, or a combination of pet food + home cooked food. Regarding vomiting - please check food timings, overdue deworming etc. Hows his stools? you may need to add some meds to enhance emptying of stomach contents down the intestines, if he vomits the food as it is.

If your dog has vomited it is fine, no botheration, our domestic lizards are harmless,& cats eat them & even some human beings also do eat that I have noted it does not matter any thing to your dog, be tension free, of course there are poisonous lizards also, even after eating the contents should go to blood to see the symptoms, if your dog has lose motion, give antimalarial medicines, do not worry,

brushing your dog and oral hygiene

Master of sciences, B.V.Sc. & A.H.
Veterinarian, Salem
Did you know that regularly brushing your dog's teeth and providing her with a healthy diet and plenty of chew toys can go a long way toward keeping her mouth healthy? Many pooches show signs of gum disease by the time they're four years old because they aren't provided with proper mouth care—and bad breath is often the first sign of a problem. Give your dog regular home checks and follow the tips below, and you'll have a very contented pooch with a dazzling smile.

1. The Breath Test

Sniff your dog's breath. Not a field of lilies? That's okay—normal doggie-breath isn't particularly fresh-smelling. However, if his breath is especially offensive and is accompanied by a loss of appetite, vomiting or excessive drinking or urinating, it's a good idea to take your pooch to the vet.

2. Lip Service

Once a week, with your dog facing you, lift his lips and examine his gums and teeth. The gums should be pink, not white or red, and should show no signs of swelling. His teeth should be clean, without any brownish tartar.

3. Signs of Oral Disease

The following are signs that your dog may have a problem in his mouth or gastrointestinal system and should be checked by a veterinarian:

Bad breath
Excessive drooling
Inflamed gums
Tumors in the gums
Cysts under the tongue
Loose teeth
4. The Lowdown on Tooth Decay

Bacteria and plaque-forming foods can cause build-up on a dog's teeth. This can harden into tartar, possibly causing gingivitis, receding gums and tooth loss. One solution? Regular teeth cleanings, of course.

5. Canine Tooth-Brushing Kit

Get yourself a toothbrush made especially for canines or a clean piece of soft gauze to wrap around your finger. Ask your vet for a toothpaste made especially for canines or make a paste out of baking soda and water. Never use fluoride with dogs under six months of age—it can interfere with their enamel formation. And please do not use human toothpaste, which can irritate a dog's stomach. Special mouthwash for dogs is also available—ask your vet.

6. Brightening the Pearly Whites

Taking these steps will make brushing a lot easier for the both of you:

First get your dog used to the idea of having her teeth brushed. Massage her lips with your finger in a circular motion for 30 to 60 seconds once or twice a day for a few weeks. Then move on to her teeth and gums.
When your pooch seems comfortable being touched this way, put a little bit of dog-formulated toothpaste or a paste of baking soda and water on her lips to get her used to the taste.
Next, introduce a toothbrush designed especially for dogs—it should be smaller than a human toothbrush and have softer bristles. Toothbrushes that you can wear over your finger (or a clean piece of gauze) are also available and allow you to give a nice massage to your dog's gums.
Finally, apply the toothpaste to her teeth for a gentle brushing, as in step 7.
A veterinary exam beforehand may be helpful to find out if your dog's gums are inflamed. If your dog has mild gingivitis, brushing too hard can hurt her gums.
7. Brushing Technique

Yes, there is actually a technique! Place the brush or your gauze-wrapped finger at a 45-degree angle to the teeth and clean in small, circular motions. Work on one area of your dog's mouth at a time, lifting her lip as necessary. The side of the tooth that touches the cheek usually has the most tartar, and giving a final downward stroke can help to remove it. If your dog resists having the inner surfaces of her teeth cleaned, don't fight it—only a small amount of tartar accumulates there. Once you get the technique down, go for a brushing two or three times a week.

8. Know Your Mouth Disorders

Getting familiar with the possible mouth problems your dog may encounter will help you determine when it's time to see a vet about treatment:

Periodontal disease is a painful infection between the tooth and the gum that can result in tooth loss and spread infection to the rest of the body. Signs are loose teeth, bad breath, tooth pain, sneezing and nasal discharge.
Gingivitis is an inflammation of the gums caused mainly by accumulation of plaque, tartar and disease-producing bacteria above and below the gum line. Signs include bleeding, red, swollen gums and bad breath. It is reversible with regular teeth cleanings.
Halitosis—or bad breath—can be the first sign of a mouth problem and is caused by bacteria growing from food particles caught between the teeth or by gum infection. Regular tooth-brushings are a great solution.
Swollen gums develop when tartar builds up and food gets stuck between the teeth. Regularly brushing your dog's teeth at home and getting annual cleanings at the vet can prevent tartar and gingivitis.
Proliferating gum disease occurs when the gum grows over the teeth and must be treated to avoid gum infection. An inherited condition common to boxers and bull terriers, it can be treated with antibiotics.
Mouth tumors appear as lumps in the gums. Some are malignant and must be surgically removed.
Salivary cysts look like large, fluid-filled blisters under the tongue, but can also develop near the corners of the jaw. They require drainage, and the damaged saliva gland must be removed.
Canine distemper teeth can occur if a dog had distemper as a puppy. Adult teeth can appear looking eroded and can often decay. As damage is permanent, decayed teeth should be removed by a vet.
9. Chew on This

chew toys can satisfy your dog's natural desire to chomp, while making his teeth strong. Gnawing on a chew toy can also help massage his gums and help keep his teeth clean by scraping away soft tartar. Ask your vet to recommend toxin-free rawhide, nylon and rubber chew toys.

P.S.: Gnawing also reduces your dog's overall stress level, prevents boredom and gives him an appropriate outlet for his natural need to chew.

10. Diet for Healthy Teeth

Ask your vet about a specially formulated dry food that can slow down the formation of plaque and tartar. Also, avoid feeding your dog table scraps, instead giving him treats that are specially formulated to keep canine teeth healthy.

My Dog is not eating. Her mouth has a terrible foul smell and has developed red rashes between her hind legs and under the tail. She has even become very aggressive and grumpy, and would not let anyone try to get her active.

MVSc, BVSc
Veterinarian,
How old is your pet? the foul smell could be from the dental disease. Kindly get her oral cavity evaluated for any dental disease/loose tooth/tarter/tooth root abscess etc. From a qualified Vet. These explorations are done generally under sedation. Take care.

Monsoon Concerns - Leptospirosis.!!!!

MVSc, BVSc
Veterinarian,
Monsoon Concerns - Leptospirosis.!!!!
Monsoon may be a great time to go outdoors with your pets and enjoy the rains. But be aware of the hidden dangers.

- leptospirosis is around and can cause lethal liver and kidney disease in dogs.
- water logging in metro cities can be a source of such fatal infections. Transmitted via urine of rats/dead rats --> Dogs can readily become infected despite vaccinations.
- common in farms too, wherever there is rat population.
- leptospirosis is a contagious to humans as well, and infected dogs, their urine becomes an important carrier for humans.
- initial signs include vomiting, jaundice, reduced urination, kidney failure.
- if not identified and treated early, it can become fatal.
- early diagnosis and specific treatment can save your pet.
- proper precautions and hygiene can save your family from exposure.
- do not let your pets walk through, or drink from water puddles.

Please speak to us for more information on this.
Have a safe monsoon!

TIPS FOR YOUR PET IN HOT SUMMER

By following a few simple rules, it is easy to keep your pet safe while still having fun in the sun"
Take these simple precautions to help prevent your pet from overheating. And if you suspect your pet is suffering from heat stroke, get help from your veterinarian immediately.
1)Visit the Vet:
A visit to the veterinarian for a early summer check-up is a must. Make sure your pets get tested for parasitic infestation, if any. Ask your doctor to recommend a safe flea and tick control program.
2)Made in the Shade:
Pets can get dehydrated quickly, so give them plenty of fresh, clean water when it's hot outdoors. Make sure your pets have a shady place to get out of the sun, be careful to not over-exercise them, and keep them indoors when it's extremely hot.
3)Know the Warning Signs:
Symptoms of overheating in pets include excessive panting or difficulty breathing, increased heart and respiratory rate, drooling, mild weakness, stupor or even collapse. They can also include seizures, bloody diarrhea and vomit along with an elevated body temperature of over 104 degrees. Animals with flat faces, like Pugs and Persian cats, are more susceptible to heat stroke since they cannot pant as effectively. These pets, along with the elderly, the overweight, and those with heart or lung diseases, should be kept cool in air-conditioned rooms as much as possible.
4)No Parking:
Never leave your animals alone in a parked vehicle. On a hot day, a parked car can become a furnace in no time-even with the windows open-which could lead to fatal heat stroke.
5)Make a Safe Splash:
Do not leave pets unsupervised around a pool-not all dogs are good swimmers. Introduce your pets to water gradually and make sure they wear flotation devices when on boats. Rinse your dog off after swimming to remove chlorine or salt from his fur, and try to keep your dog from drinking pool water, which contains chlorine and other chemicals that could cause stomach upset.
6)Summer Style:
Feel free to trim longer hair on your dog, but never shave your dog: The layers of dogs' coats protect them from overheating and sunburn. Brushing cats more often than usual can prevent problems caused by excessive heat. And be sure that any sunscreen or insect repellent product you use on your pets is labeled specifically for use on animals.
7)Street Smarts:
When the temperature is very high, don't let your dog linger on hot asphalt. Being so close the ground, your pooch's body can heat up quickly, and sensitive paw pads can burn. Keep walks during these times to a minimum.
8)Avoid Chemicals:
Commonly used flea and tick products, rodenticides (mouse and rat baits), and lawn and garden insecticides can be harmful to cats and dogs if ingested, so keep them out of reach. When walking your dog, steer clear of areas that you suspect have been sprayed with insecticides or other chemicals. Keep citronella candles, oil products and insect coils out of pets' reach as well. Call your veterinarian if you suspect your animal has ingested a poisonous substance.
9)Party Animals:
Taking Fido to a backyard barbeque or party? Remember that the food and drink offered to guests may be poisonous to pets. Keep alcoholic beverages away from pets, as they can cause intoxication, depression and comas. Similarly, remember that the snacks enjoyed by your human friends should not be a treat for your pet; any change of diet, even for one meal, may give your dog or cat severe digestive ailments. Avoid raisins, grapes, onions, chocolate and products with the sweetener xylitol.
10)Fireworks Aren't Very Pet-riotic:
Exposure to lit fireworks can potentially result in severe burns or trauma to curious pets, and even unused fireworks can be hazardous. Many types of fireworks contain potentially toxic substances such as potassium nitrate, copper, chlorates, arsenic and other heavy metals.

Your dog can have inner ear infection. Specially the side whr the head is tilted. Explains both salivation (vomiting sensation) and pain (tilting of head, loss of hunger, loss of sleep). Improper walking can happen if the balance between both of the ears is lost for any reason. Imagine your self rotating 20 times. In your dogz case it could an infection and no actual neurological issue. Kindly ask your doctor to do an otoscopy for the ear and send swab samples for culture test. Good luck.
