How to Identify Common Pet Problems ?

To treat a foot pad injury, first rinse the affected foot under cool water to remove debris. Next, apply an antibacterial ointment or solution, like Neosporin, on the wound. Finally, place a non-stick telfa pad over the foot pad(s) and lightly wrap with vet wrap or an ace bandage.
The best thing you can do is to apply anti-bacterial wash and cover the paw with a bandage until the pad has healed. If your dog has a loose flap of pad you`ll need to wait for this to come off, which it will do on its own or you can ask your vet to trim it off. Your dog`s footpads are naturally rough.
If the affected area is in the paws, consider soaking your pet`s feet in warm water with Epsom salt for 15 minutes. This can help relieve the pain caused by paw pad hyperkeratosis. Make sure to pat your dog`s paws dry to prevent infections from entering the damaged skin.
Often called lick granuloma, it`s a form of self-trauma where the dog continuously licks a small area, most commonly the paw that becomes raw and inflamed. This behavior is related to stress, boredom or compulsiveness. Excessive licking can damage the tissues further and can also delay healing.
Infectious. The feet and paws are often red (inflamed) and swollen. There may be nodules (bumps) or fungal lesions (kerions), ulcers, or discharge (pus) from the lesions. There is often hair loss and the dog may lick the feet constantly.
Apply antibiotic ointment, such as Polysporin, to the burned foot pad and bandage the paw. Daily bandage changes and close monitoring of the injury are important. Report any changes to your veterinarian.
Other over-the-counter medications safe to use on canine skin include Neosporin—an antibiotic ointment—and Benadryl cream, a topical pain reliever. “Hydrocortisone cream is usually more effective than Benadryl cream,” says Butzer. “But oral Benadryl can help with reducing inflammation in the affected area.”
Yes, you can put Vaseline on your dog to treat skin conditions, including hyperkeratosis.
Nasal hyperkeratosis can be relieved by applying certain oils to a dog`s nose. Over time, the keratin overgrowth can become brittle and fall off. We like products that contain several different oils and butters (such as Shea butter, coconut oil, and olive oil) designed to absorb in layers on your dog`s nose.
A torn foot pad does not hold stitches well, so cuts and punctures take longer to heal. Walking on the injured foot often opens up the wound and further delays healing. And if infection sets in, your dog may end up with more than just foot problems.
But our vet is well aware that not all dogs love shoes, which is why he has a second option, too — and you probably already have it in your home: Vaseline! Applied to the paws, the petroleum jelly creates a protective barrier. It also helps heel cracked paws.
Make a bowl of salt water and place your dog`s paws in the water to soak for at least 10 minutes. You can also use terry cloths or sponges to make compresses to use on injured skin. Repeat this process two to three times a day for optimal effects.
Pododermatitis is defined as inflammation of the skin of the paw. Affected tissues may include interdigital spaces, footpads, nail folds (paronychia), and nails. Cases of canine pododermatitis are common in general practice. One or more feet may be affected.
Pododermatitis refers to the inflammation of the skin on the paw pads of your dog. It is a common skin problem that can affect one or more of your dog`s paws. It usually targets the paw pads, nails, nail folds, and interdigital space or the skin area between the toes and the paw pads.
Don`t use human lotion on the dogs` pads, it may soften pads too much and lead to more issues. Instead look into pad moisturizers specifically designed for a dog`s dried out paws. While rubbing in the lotion give the dog a paw massage by rubbing between the pads and up in between each toe.
Paw pad hyperkeratosis refers to when thickened skin or extra skin grows on your dog`s paw. The skin`s appearance may vary, but it often resembles thick hair on your dog`s paw pads. Thus, it`s often called “hairy feet”. Hyperkeratosis occurs due to a protein inside your dog called keratin.
Paw pads can take anywhere from 14 to 21 days to heal, but it depends on the wound and the reason for the bleeding. Deeper punctures will take longer to heal than cracked, dry paw pads and may require your dog to take it easy for a few days so as to not put too much pressure on the paw.
Carpal Pad: The carpal pad is a small pad located above the dewclaw. It`s found on the forelimb (or front leg) and is only found in animals that walk on their digits. Metacarpal/metatarsal pad: This heart-shaped pad supports more of the dog`s weight since it is located in the center of their foot.
Coconut Oil for Your Dog`s Paws

If you find that your pup`s paws are dry or cracked, you can use coconut oil to help soothe and heal them. Make sure to rub the coconut oil thoroughly into your dog`s paws, or your dog will mistake this treatment for a snack and lick off all of the oil!

There is no cure for these conditions. To treat large areas of scaly skin, your doctor may suggest rubbing special emollients into the skin.
If your dog is in pain from the hyperkeratotic paw pads, it may help have excess skin trimmed off. Make an appointment with your vet, and if you and your vet are comfortable, your vet can teach you how to trim your dog`s paws.
Should You Moisturize Your Dog`s Paws? You should moisturize your dog`s paw pads if they are cracked, peeling, or too dry.
Coconut oil can add moisture to your dog`s skin and prevent flaking. It also helps freshen up a dog`s coat if used with a light touch. To use it topically, simply rub a very small amount onto your hands and then gently pat the coat, run your fingers through the fur, and massage a little down onto the skin.

Q. What is the best way to train your dog on a pee pad? He can go on the pee pad if I bring him to the pad if I don’t he makes an accident.
ANSWER : A. Train your dog using a positive reinforcement method. Since your dog will use the pad when you bring it to him, reward him immediately for urinating on the pad. First, teach your dog to associate the word “good” with a treat (or use a special device called a “clicker” in place of a verbal “good”). Then, say “good” or “click” when you dog urinates on the pee pad and reward him as soon as he finishes. Repeat this training over and over until your dog understands that peeing on the pad equals reward. Then, begin to move the pad away from your dog and bring him to the pad wherever it is. Again, reward when he goes on the pad. It is all about making it “fun” to pee on the pad (reward) and not fun to pee anywhere else (no reward). To learn more about “clicker training” and/or positive reinforcement training, I recommend purchasing a good book on training using positive reinforcement techniques. Or, I or another of the experts on this site, would be happy to consult with you to guide you through the steps and make this a positive experience for both you and your dog.

Q. Why does a dogs pads on his paws turn such a pink color?
ANSWER : A. I’m confused here. Are your dogs paw pads typically black, but they turn a reddish pink? You may want to see your veterinarian about this to make sure there isn’t anything wrong with his paw pads. I’ve met dogs who have extremely fragile paw pads due to some bad genetics.. they end up getting injured on their paws very easily. I’ve met dogs who are unable to even walk on cement without wearing little doggy booties. It could be that your dog is dealing with some serious discomfort, and you want to get that checked out immediately.

If your dogs paw pads just seem a little bit irritated, you may want to try something like “Musher’s Secret” on them. This is an ointment that you rub on your dogs paw pads to keep them healthy, and smooth. I use this in the winter when there is rock salt all over the ground.. it keeps her paw pads from getting irritated and tearing open. It’s like lotioning your skin to keep it from getting dry and cracked. If you think your dog is dealing with something that is a little more extreme than just some dry irritated paw pads, then see your vet immediately instead of purchasing the Musher’s Secret.

Q. Stiff course hair on the side of his pads making them sore, what could this be and what can I do about it?
ANSWER : A. It could be a localised dermatitis or pyoderma. I would recommend having it checked by your vet and maybe some skin scrapes done. This will enable you to treat correctly.

Q. Russian blue mix cat – usually velvet soft coat but hair on back hind qtrs. is thinning, remaining hair seems less velvety than normal
ANSWER : A. Changes in coat appearance can be caused by a number of things. In older cats, hair loss or changes in coat and skin confirmation may indicate a metabolic issue such as thyroid problems. Cats can begin to lose hair and may also show other changes such as weight changes or appetite changes. Blood work is usually done to check for this, and most pets do very well with a daily medication treatment.

Hair loss can also be caused by mites on the skin, external parasites or even skin and fungal infections. These may cause red bumps or sores to appear on the skin in addition to the hair loss and coat changes. Your vet can take a skin scraping of the area to check for mites and infections, and a preventive flea treatment can remove any external parasites. If an infection or mites are present, your vet can also prescribe an antibiotic or topical cream to treat.

After any treatment it may take a month or two for completely bald patches to grow back in. This is normal as the skin and follicles need some time to heal prior to beginning the hair growth cycle again.

Q. Fleas? First noticed scabs & small lumps under chin & neck. Used hydrocotizone spray, flea collar, spray, baths…Is licking, has hair loss & swelling
ANSWER : A. If you are currently treating for fleas with a flea prevention treatment, several things could be happening. It could be that your pet is experiencing a flea-bite allergy, even if the fleas themselves are gone, which is very common. This causes small, red, itchy bumps to appear on the body where fleas have previously bitten the area. If your pet is allowed to scratch or chew at these spots, it could lead to a bacterial infection under the skin which can become red, painful, hot to the touch or even cause the hair to be lost in the affected area. Making an appointment with your vet can determine if this is the case and treatment usually involves allergy medications and any antibiotics or anti-fungals needed to clear up a secondary infection.

Another cause of skin changes, swelling and hair loss are hormonal imbalances. Thyroid problems, adrenal gland problems and other hormone produces in the body can cause changes to appear on the coat and skin in affected animals. You may also notice other signs such as changes in appetite, thirst, urination or even in your pet’s weight. A set of blood tests from your vet can determine if this is the case. Most of these conditions are treated successfully with the addition of a daily medication to balance the hormones.

Q. My dog is bleeding out of rearend after
going to vet for a leg trouble the vet says
it is stres
ANSWER : A. It could be many things causing the problem. If it is an unneutered female it could be a season, if it is in the urine it could be a cystitis which could be set of by stress amongst other things. It could be from the anal glands or it could be from the lower intestinal tract. If it is the latter I would be careful what pain relief medication you are giving as some can cause bleeding in the GI tract such as meloxicam. I would recommend having a recheck with your vet to establish where the bleeding is coming from as some causes may require treatment or a change in current treatment.
