Experienced and professional animal trainer provide their insights in answering this question :
A. Dark and brown teeth are covered with tartar and possibly stains from the coloring or dyes put in dog food.
I would recommend brushing your pets teeth daily and also giving her a higher quality food which won’t stain the teeth so readily. Also feeding her a dry kibble instead of wet food will help the teeth as well.
If there is staining there this in most cases won’t be removed completely but getting your pets teeth cleaned and fluoride treated will remove the tartar and help keep your pets dental hygiene up to par.

How to Identify Common Pet Problems ?

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

Discoloration (Brown Teeth): Yellow or brown discoloration of the teeth along the gum line is a good indication of tartar and plaque buildup. Gingivitis (Swollen Gums): Red and swollen gums will surround the teeth. The inflamed gums will often have plaque at the base of the teeth as well.
Always be sure to take your dog to a veterinary dentist as soon as you notice any discoloration or other signs of dental problems so that the issue may be correctly diagnosed and treated.
Most commonly, dental disease is the result of tartar buildup on a cat`s teeth. Tartar can be easily identified by its tan or brown color. As a cat eats, some of the food gets stuck to its teeth and turns into plaque.
If you notice black or brown spots on your dog`s teeth, you`re probably looking at plaque and tartar build up. Plaque and tartar like to live along the gumline and in tiny crevasses. Again, this stuff builds up quickly!
No. Human toothpastes contain ingredients that should not be swallowed. If it is swallowed, it can cause an upset stomach or digestive disturbances. Some human toothpastes contain high levels of sodium which may even make your pet ill, while others may contain xylitol (artificial sweetener), which is toxic for dogs.
The most effective home remedy for tooth decay is daily brushing, especially on the chewing surfaces in the back of the mouth. You can try certain tartar-removing chew toys and dental treats, too.
Given that gingivitis leads to periodontitis, most cats with periodontitis will show signs of gingivitis (redness, swelling, bleeding along the gingiva at the base of the teeth), and may also be reluctant or unwilling to eat, drool, turn their heads to the side when chewing, and develop halitosis.
Wear and gum disease are more common when your dog or cat is between the ages of five and 10. Elderly pets may eventually lose teeth due to tooth decay or gum disease, and their teeth may show considerable wear.
A dying tooth may appear yellow, light brown, gray, or even black. It may look almost as if the tooth is bruised. The discoloration will increase over time as the tooth continues to decay and the nerve dies. If you experience any symptoms of a dying tooth, it`s important to see your dentist right away.
If left unaddressed, dental disease can cause progressive issues that put your dog`s entire body and overall health at risk.
An abscessed tooth usually has a dark halo visible around the tooth roots on an X-ray. Your vet will also perform additional X-rays and a full dental examination during the procedure.
Rotten and decaying teeth are painful and dangerous for dogs. Not only can they make your pet not want to eat or drink, but they can lead to other diseases. Dental disease puts dogs at risk for the development of heart disease.
The Benefits of Raw Carrots

This chewing mechanism helps clean your dog`s teeth and gums by removing residual food pieces and help clear plaque from tooth surfaces. Carrots can make great treats for your dog, due to their low-calorie content, especially if you need a larger quantity of treats when training.

No. Similar to human toothpaste, you should never brush your dog`s teeth with baking soda. Baking soda is harmful for dogs if swallowed because it is highly alkaline, which makes it upsetting for canine stomachs and digestive tracts.
And while it can be relatively easy to see that a dog has leg or knee problems, you may struggle to spot oral health issues. However, in the same way that dental problems can be quite painful in humans, dogs experience the same pain without us realizing it.
MAJOR / GRADE 3

Plaque and tartar formation is heavy. Pockets of bacteria and debris have accumulated to form further pockets of infection along the teeth. The infection has destroyed tissues around the teeth that hold them in place, and some have become loose. The gums appear bright red and bleed freely.

Dental disease, also known as periodontal disease, is a condition in which the tissues supporting the teeth become inflamed. In its most mild form, periodontal disease is associated with gingivitis, or inflammation of the gums.
While you may think of dental disease as being primarily a cosmetic issue, the truth is that dental disease can also be painful for pets. Inflammation of the gums (gingivitis) can be uncomfortable on its own, while some pets may have more serious issues such as fractured teeth, tooth root abscesses, and oral tumors.
Most likely these dark spots are either 1) crown fracture or wear with pulp exposure or near pulp exposure, 2) chip fracture or wear with tertiary dentin, or 3) discoloration.
A common misconception is that wet cat food causes tooth decay in cats, we now know that this is not the case! So prepare a healthy and nutrient-dense meal for your cat, and combine wet and dry cat food from the most recognised and trustworthy brands in the pet food industry.
Cat tooth extraction is necessary in several cases, including advanced stage gum disease. Advanced periodontal disease can cause loss of viable teeth. The teeth that are severely affected should be extracted before the damage is permanent.
Daily brushing is the absolute BEST way to prevent dental disease. Toothpaste specially designed for cats is readily available in flavors they`ll enjoy. Do NOT try to brush your cat`s teeth with “people” toothpaste; if fluoride toothpaste is ingested, it can make your cat severely ill.
Tooth decay discolors teeth in several ways. Cavities are caused by plaque that isn`t removed from a tooth and begins to destroy the enamel of the tooth, turning it brown. Secondly, a cavity eats through the enamel and exposes the tooth`s internal dentin, which is naturally darker than the outer surface of the teeth.

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. What could be causing my dogs hair to fall out causing bald spots?
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.

If there is no relief or not enough, consider getting your pet checked by a veterinary dermatologist and having allergy testing done.
