How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

Red ulcerative lesions may be present on the hard palate, or roof of the mouth as well as affecting the lips. Cauliflower or mushroom-shaped masses are often present on the tongue. A goal of treatment is to address the underlying allergic cause. Common causes of allergies are environmental or specific food antigens.
Supplemental antibacterial measures, such as topical chlorhexidine rinses or gels, may be prescribed by your veterinarian. In severe cases, topical anti-inflammatory preparations may provide comfort. Discomfort caused by the ulcers can make it difficult to brush your pet`s teeth and give oral medications.
What is periodontal disease in dogs? Periodontitis bacteria can infect your dog`s oral cavity. Usually, this disease silently invades the mouth and you won`t see any pervasive signs or symptoms until it advances. However, gum disease may cause chronic pain, gum erosion and loss of bone and teeth.
Superficial dog eye ulcers may heal on their own, but topical antibiotics are often recommended to reduce the risk of infection and further damage to the eye. More severe ulcers will not go away on their own and will require veterinary treatment.
They can be white, red, yellow or grey in colour and swollen. It`s possible to have more than one mouth ulcer at a time and they may spread or grow. Mouth ulcers shouldn`t be confused with cold sores, which are small blisters that develop on the lips or around the mouth.
Dog saliva is antibacterial, but it probably won`t heal wounds. Dogs often lick their wounds in order to clean them. There may be healing properties in a dog`s saliva, and this may be another reason that they lick their wounds.
One commonly prescribed antibiotic for oral infections is Clindamycin which is generally given twice daily. Do not give human pain medications to animals at any time without the approval of your veterinarian.
The unique bacteria living in your dog`s mouth, coupled with the various bacteria-ridden things your dog may eat, are more than enough reason to regularly clean his mouth. A lack of regular dental care will lead to all sorts of health issues, including periodontal disease, halitosis, and tooth decay.
That`s why it`s important to never share your own mouthwash with the dog – not even a splash in their water dish is OK. Ingredients in human mouthwash, ranging from xylitol (very toxic to pets) to fluoride can make dogs sick.
What does a dog tooth abscess look like? The most common signs of a dog tooth abscess include redness and swelling on the gums surrounding the affected tooth and swelling under the eye. In some cases, there could be pus draining from the surface of the swelling.
Recovery of Pressure Sores in Dogs

Some sores are able to heal in four to six weeks, whereas sores that require surgical intervention may take longer to fully heal.

Yes, stomach ulcers can be painful for dogs. If your dog is showing signs of stomach pain, such as lethargy, crouching or arched back, or guarding their stomach, you should take them to see your veterinarian as soon as possible.
Cold sores develop on the lips, normally on the junction between the lips and the rest of the facial skin, whereas mouth ulcers develop inside the mouth. Cold sores are caused by the herpes simplex virus, and the fluid from the blisters is extremely contagious.
Mouth sores often go away in 10 to 14 days, even if you do not do anything. They sometimes last up to 6 weeks. The following steps can make you feel better: Avoid hot beverages and foods, spicy and salty foods, and citrus.
Most mouth ulcers are usually harmless and resolve by themselves within 10 to 14 days. Other types of mouth ulcers, such as the aphthous variety or those caused by herpes simplex infection, need topical treatment (such as a mouthwash, ointment or gel).
Dogs` saliva prevents some bacteria from growing. However, this is only minorly effective, and the benefits largely stop there. There is nothing in a dog`s saliva that can make wounds heal faster. They don`t heal their wounds by licking; they simply keep them clean to prevent infection.
Your veterinarian may prescribe medications to relieve pain and discomfort. Once a wound has begun to heal, it is no longer as painful. Non-steroidal anti-inflammatory drugs (NSAIDs) such as meloxicam (Metacam®), deracoxib (Deramaxx®), or carprofen (Rimadyl®) are often prescribed.
A pharmacist can recommend a treatment to speed up healing, prevent infection or reduce pain, such as: antimicrobial mouthwash. a painkilling tablet, mouthwash, gel or spray. corticosteroid lozenges.
Instead of toothpaste, use plain warm water, a very diluted saltwater solution or one of the excellent tooth cleansers now available for dogs and cats. Most tartar formation occurs on the outer surfaces of the teeth; so give those areas a good scrubbing. If your pet is cooperative, then try for the inner surfaces.
Your dog can take the majority of antibiotics that humans take for bacterial infections. Any antibiotics you give your pet, however, should be prescribed by your veterinarian.
It`s important never to give paracetamol to your dog unless your vet tells you to – it can be very dangerous if it`s given incorrectly.” Claire explains that you should always head to your vet for advice, including if your pup accidentally digests a painkiller.
For the best dog dental hygiene, brush two to three times a week to help keep tartar buildup in check. You can also keep your pup`s breath fresh by rinsing their mouth regularly with a solution of 1/2 teaspoon salt and 1 teaspoon baking soda in 1 cup of warm water.
Do not use human toothpaste – it is not formulated to be swallowed. Once your dog has accepted the taste of pet toothpaste, apply a small amount to the cloth and rub it over the teeth. Once your dog is used to you rubbing his teeth with a cloth, it`s time to start using a toothbrush.
The Listerine gets rid of fleas on the dog, and can also be used to kill fleas on the household spaces where they may have spread. The diluted Listerine is safe to use on a dog`s skin because the water takes away some of the bite that could sting.

Q. PLEASE HELP, PLEASE. MY KITTEN is foaming at the mouth!! We just gave her a bath and all of the sudden her mouth is foaming…My parents are at work!
ANSWER : A. Hi, when a cat foams normally means that she noticed a bad taste in the mouth, probably in your case some shampoo/soap went inside the mouth and is foaming. Rinse the mouth with plain water and she will be fine.

Q. My dog has bad rotted loose teeth. She is older and when I got her it was this way. Now I am finding out more and want her to have better life quality
ANSWER : A. She will need dental treatment in order to remove any infected material in her mouth, which can cause heart and kidney infections if left in place long term. Any loose and damaged teeth should be removed as these are a constant source of discomfort and infection in her mouth. There are many home care options from brushing, medicated dental chews and mouth rinses to drinking water additives all of which will help to maintain a cleaner, healthier mouth after her dental procedure

Q. How should I introduce my puppy to her crate?
ANSWER : A. A crate is very useful for making sure your dog is safe during the night while you sleep, for traveling, or for when you have guests, amongst other reasons for crate training. It is important that you slowly introduce your puppy to her crate; do not rush her. Using kibble or a small treat as a lure, place the food item inside the crate so that she will go inside. Close the gate gently, not suddenly, since you do not want the puppy to be frightened. You might also include one of the puppy’s comfort toys and a familiar blanket inside the crate. Gradually increase the puppy’s time inside the crate with the gate latched until she feels at ease going into her crate at your command.

Q. My cat is dripping saliva from his mouth and Its gooey it also smells..what does it mean?? And what can I do??
ANSWER : A. Drooling can indicate getting something that tasted bad, nausea, tumor of the mouth, throat or esophagus, mouth pain or something caught in the mouth. I recommend getting him in to see your vet as soon as possible for an oral exam and possibly x-rays to determine the cause for his symptoms and get him started on treatment.

Q. My 10 yr Chow mix chews a sore on her front leg unless we keep a “cone collar” on her. What can we do?
ANSWER : A. Lick Granulomas (chewing sores on body parts) are very common in dogs and can be triggered by an initial health event, and then become a behavioral issue. Breaking the “habit” of licking can be hard at times, and takes a lot of time and patience. It is also a good idea to make sure any initial or underlying problems in the area (such as infections or parasites) is cleared up.

While the cone or covering the area with long socks if on the forearm or foot is a traditional method of breaking the habit, there are new products out called “no lick strips” which can be applied onto a bandage over the affected area. These strips utilize a minor form of positive punishment- when the dog licks the strip he gets a minor electrostatic shock or bad taste in his mouth, deterring him from continuing. The strips have had good success with use when compared to just using an Elizabethan collar.

Treating any underlying stress or anxiety can also help to decrease licking behaviors. Calming medications and treats, removing the stressors, providing a safe place for your dog to “hide” during stress or anxiety, or even using calming pheromones can all help with stress reduction.

Q. Bactterial infection on paws can it spread tto her mouth? to humans? is there a betagen alternative
ANSWER : A. Yes, occasional bacterial infections do spread to the skin around the mouth from grooming. Some infections would also be transferable to humans but this is quite rare; I recommend hand washing in warm, soapy water with or without an alcohol based hand sanitizer after handling her as a precaution. There are dental antiseptic pastes which are more adhesive/sticky and work well around the mouth such as dentisept ointment

Q. My dog just had a spoon splint removed after 33 days on back leg.Was fine at vet.An hour later is swollen and bleeding.How do I care for pressure sore
ANSWER : A. If the reason for the splint (fracture, I’m assuming) has properly healed – and ideally this would have been determined with an x-ray – then you can try to manage the pressure sore at home. Soaking in a warm Epsom salts bath (follow the directions on the package for diluting for soaking) for 10 minutes every 4 hours will possibly help with the swelling, and discourage infection. Keep it clean – if he’ll tolerate wearing a child’s sock on the foot that might help. If the sore starts smelling bad or has cloudy discharge it’s infected, and you’ll need antibiotics to treat that.

I would recommend that you call the vet who put the splint on to report this. If it looked good when the splint came off I would want to know (if I was his vet) that this sore had just popped up an hour later. That seems strange to me.
