Medical Reasons Dogs May Stink

Secondary yeast or bacterial infections on the skin or inside the ears remain the most common medical reasons dogs might smell awful. Allergies often begin the process, which leads to scratching and licking that open the door for infections.

Dogs due for a bath tend to smell, but a bath often rectifies this odor. However, sometimes baths don`t get rid of odor, contrary to our expectations. Anal gland issues, skin infections, excessive sebum from overbathing, and ear infections are the most common causes of dog odors that linger after showers.
Dogs aren`t exempt from getting dirty and smelly, but sometimes the cause of odors on a dog isn`t just because it`s time for a regular bath. Various infections, dental issues, and even run-ins with wildlife can cause seemingly unexplained odors on a dog.
Rule of thumb: You can bathe your dog about once a month unless they seem smelly/dirty, or you notice it over-dries their skin. Note: Be sure to avoid over-bathing. Dry skin caused by over-bathing can be very uncomfortable. Dogs need a certain amount of oil to maintain a healthy coat and skin.
Diet is one factor that affects your dog`s smell. So if you want to improve your dog`s smell naturally, avoid feeding them low-quality food. Instead, add more raw meat and dog-friendly fruits and vegetables to your dog`s diet. Some fresh herbs like parsley will also help to the neutralize your dog`s smell.
According to BeChewy, medium and long coat dogs should bathe every four to six weeks, and owners of dogs with short coats should bathe their pets somewhere between every month and every three months. Dog owners should be warned not to wash their pup`s coats too much, though.
While parasites such as fleas, lice and mites do not create an odour, they cause intense itching. The dog can lick, chew and scratch to the point that they develop secondary skin infections.
Mite infestations can cause a foul odor in your dog`s ears. You may also see a buildup of dark debris in your dog`s ears, similar to coffee grounds. As you examine your dog`s ears, look for redness in the ear canal as well as the outer ear, as this is another sign of ear problems in dogs.
If your dog`s feet smell like Fritos, they probably has a buildup of Pseudomonas or Proteus on the surface of their paws. These are two types of bacteria that are commonly found on dog paws, but don`t cause any issues or illness.
Unlike other breeds, German Shepherds don`t need to bathe often. In fact, it`s best that they only bathe every 3-4 months. German Shepherds have a double coat – the topcoat and the undercoat. The topcoat protects them from sun exposure, dust and other particles.
Wash your dog with apple cider vinegar mixed with shampoo. Use 1 tablespoon vinegar, and 1 tablespoon Dawn dish soap mixed with 1 cup water. Vinegar neutralizes smell and works as an anti-fungal. Use an anti skunk spray shampoo.
Groomers also use conditioners like our Plush Puppy T.L.C Leave-in or Rinse out conditioner to give your dog`s coat a shine, as well as a fresh fragrance. This conditioner comes in a spray that can be left in your dog`s coat, or rinsed out, whichever works best for your pet.
At the top of the list? Citrus. Most dogs can`t stand the taste and smell of oranges, lemons, and grapefruit.
In general, it`s wise to bathe your dog early in the day — especially if they have thick fur — so they`ll be dry before their evening walk. Adapt to the animal`s lifestyle: If you have a dog that lives outside, you can still give them a good cleaning, even when it is too cold to bathe a dog outdoors.
Bathing frequency will depend on your pet`s species, breed, coat length, and lifestyle. In general, moderate- to long-coated dogs should be bathed every four to six weeks, while short-haired breeds may go for months without a bath.
No, it is not recommended that you use baby wipes on dogs, or any other pets. That`s because the pH level on human skin is different to dogs so baby wipes are unsafe because they may cause irritation or itching.
A daily full bath is more than what most dogs need. So a bath mixed with rinsing or wiping him down is a very good plan. You can tell if his skin is getting too dry if you see seborrhea (“dandruff”) or dry skin flakes. If his skin looks healthy – you are probably doing just fine and not over-doing it.
Allergies, hormonal imbalances, fungus, parasites and localized inflammation can lead to an overgrowth of yeast or bacteria on the skin and cause an unpleasant smell.
First, dogs have a lot of furs, which trap odors and make them difficult to remove. Dogs also shed hair all the time, which can get stuck on carpet and furniture. Additionally, dogs have a lot of bacteria in their mouths that cause odors to build up over time on everything from shoes to pieces of furniture.
A history of sudden onset, intense itching not responsive to steroids is classic for scabies mange. Affected pets scratch, lick, and bite themselves like crazy and sometimes give off a bad odor.
Interestingly enough, they can, and dogs can be trained to sniff out bugs as well! In particular, beg bugs are often detected by dogs. Other invasive bug species, such as vine mealybugs and termites, are often detected by special bug-sniffer-dogs as well to stop the bug issue from spreading more than it already has.
Sarcoptic mites can`t be seen with the eye, but you`ll definitely notice the itchy agony they trigger in your dog. These tiny mites live and feed on your dog`s skin, with the females burrowing underneath the top layer to lay eggs.
Can humans catch mange from dogs? Yes, but sarcoptic mange mites can only complete their life cycles on dogs and some other animals. This means that while human infections can still cause lots of irritation, they will be short-lived.

Q. My 10 year old male German Shepard Dog is constantly chewing at his legs, hind quarters and underbelly. No fleas or visible rash. Inside dog. Any ide
ANSWER : A. Skin problems can have a variety of causes, sometimes more than one. It is important to have the problem checked by your vet to determine if there is a medical cause for your pet’s skin issues and treat accordingly.

In pets of all ages, fleas, food allergies and exposure to chemical irritants such as cleaners and soaps can be a cause. Any one of these may not be enough to trigger the breakouts, depending on how sensitive your pet is, but a combination can be enough to start the itch-scratch cycle. Finding out the cause and eliminating it is the best course of action. With flea allergies, if your pet is sensitive enough, a single bite can cause them to break out scratch enough to tear their skin.

Check for fleas with a flea comb. Look for fleas and/or tiny black granules, like coarse black pepper. This is flea feces, consisting of digested, dried blood. You may find tiny white particles, like salt, which are the flea eggs. Applying a good topical monthly flea treatment and aggressively treating your house and yard will help break the flea life cycle.

If you use plastic bowls, this is a possible cause for hair loss, though this tends to be on the chin, where their skin touches the bowl while they eat. If you suspect this to be the culprit, try changing the bowls to glass, metal or ceramic.

Food allergies are often caused by sensitivity to a protein in the food. Hill’s Science Diet offers some non-prescription options for sensitive skin as well as prescription hypoallergenic foods for more severe cases. Royal Canin carries limited protein diets that may also offer some relief. Your vet can recommend a specific diet that will help.

Q. Which common foods are poisonous to pets?
ANSWER : A. That’s a great question. As responsible pet owners we need to be aware of food items that can be harmful to our canine or feline companions. Here are some of the most common foods proven to cause illness in our animals at home:

Chocolate: A favorite and irresistible treat amongst most humans, chocolate is considered toxic to dogs. In very small amounts it is usually not a huge issue, but with larger volumes and with darker chocolates pet owners should be concerned. Chocolate contains methylxanthine theobromine, which is similar to caffeine. Chocolate ingestion can cause vomiting, diarrhea, hyperactivity, issues with normal heartbeats, seizures, and in some severe cases, death. It is best to keep your favorite chocolate treats in a good hiding spot and out of reach of your dog or cat.

Grapes and raisins: Dogs should not consume grapes and raisins because of the risk of acute kidney failure. Most dogs experiencing grape or raisin toxicity will begin to have vomiting and/or diarrhea within 6-12 hours of ingestion. Other abnormal clinical signs include lethargy, abdominal pain, dehydration, and tremors. Kidney failure develops within 24-72 hours of the initial ingestion. There are some dogs that do not experience these devastating side effects. It is best to contact your veterinarian or veterinary emergency facility if you believe your pet has ingested grapes or raisins.

Garlic and onions: We often forget that our meals contain these two popular ingredients and will allow our furry companions a few bites or licks. Onion and garlic both can cause a type of poisoning that results in damage to red blood cells, making them more likely to rupture. They can also cause stomach upset and mouth irritation. Look for pale gums, increased breathing or drooling or any vomiting or diarrhea.

Bread dough: Unbaked bread dough is considered poisonous to our pets. The bread dough, when ingested, expands in the stomach because of the warm and moist environment. This can lead to a bloated or even twisted stomach. In addition yeast is often added to our baking products to help get bread to rise, and when this yeast is fermented it produces both carbon dioxide and alcohol. The alcohol produced can be absorbed into the bloodstream and causes dangerous drops in blood sugar, blood pressure and body temperature. Common clinical signs include vomiting or retching, distension of the stomach, weakness and collapse.

Macadamia nuts: Ingestion of these nuts are not proven to be fatal in dogs but can cause them to experience uncomfortable clinical sings, including fever, joint stiffness, vomiting, tremors and difficulty walking, especially in their hind legs. Often your pet will start to feel better after about 48 hours, but supportive veterinary care (such as pain medication) may help ease their discomfort.

Xylitol: The most common ingredient used in sugar-free gum is xylitol, which is a non-caloric sweetener. It is also found in some oral rinses, toothpastes and vitamins. Xylitol and dogs do not mix – it can cause a dangerous drop in blood sugars levels. Dogs will often display signs of disorientation, black tarry stool, tremors and seizures. If severe enough some dogs have developed liver failure. Keep your gum away from your canine companion.

Avocados: Avocados are not actually poisonous to dogs or cats but as many veterinarians can tell you the avocado pits can cause a foreign body obstruction. Avocados contain persin, which is actually toxic to the majority of pet birds. The abnormal clinical signs associated with avocado ingestion in birds include, respiratory distress, inability to perch, liver and kidney failure and sudden death.

Go forth and enjoy your favorite foods, but keep in mind which foods you should avoid sharing with your furry family members. Whenever in doubt, contact your veterinarian for healthy and safe food suggestions.

Q. Healthy German Shepherd has extremely loose stools once a day. I added 2 spoonfuls of pumpkin puree that hasn’t helped. No diet changes. Any advice?
ANSWER : A. Loose stools can be caused by a number of factors, and the first step is always to bring a stool sample to your local veterinarian to check for anything. Fecal exams can check for common bacteria and parasites in the stool that may cause chronic diarrhea.

Diet problems can also play a factor in loose stool as well as chronic illness. Dogs can be allergic to many different ingredients in the diet, however grains such as corn, wheat and soy products can be the most problematic. Adding a probiotic supplement can sometimes help such as a scoop of plain yogurt ever meal, or commercial product from your vet.

Illnesses and metabolic disorders may also cause chronic loose stools. German Shepherds are prone to a disease called Exocrine Pancreatic Insufficiency which is a problem with the pancreas (the same organ that dysfunctions in diabetes- however that is ENDOCRINE function in that case) producing enough digestive enzymes. This causes stools that may be loose, discolored grey or yellow and appear very fatty in color. Shepherds can also be prone to chronic small intestine infections that cause loose stool as well. Luckily, treatment for these conditions often just involves adding a daily digestive enzyme supplement to the food, or daily anti-biotic designed specifically for chronic bowel issues.
