If your dog is vomiting white foam, it`s important to see your veterinarian right away. They will be able to determine the cause and provide the appropriate treatment. Possible causes of vomiting white foam in dogs include: Ingestion of something that is irritating to the stomach, such as bleach or soap.
Coughing up white foam can be a sign of Kennel Cough, bloat or gastrointestinal distress. The latter two conditions are classed as emergencies, so if your dog is coughing up white foam, contact your vet or emergency care provider right away.
White foam, a makeup of mucus and fluid from a dog`s respiratory tract, can appear as vomit for several reasons. It could be because of gastrointestinal parasite infection (or other infections), pancreatitis, foreign body ingestion or consumed toxins, Dr.
Dogs suffering from pancreatitis throw up their food frequently, and this vomit could include white foam. Other symptoms include a hunched back, abdominal pain, diarrhea, loss of appetite, weakness, and dehydration. If you notice all or some of these symptoms, take your dog to the vet as soon as possible.
Possible causes of a dog vomiting or regurgitating white foam include indigestion, acid reflux, dietary indiscretions, infections, heat stroke, kidney disease, parvo, pancreatitis, and bloat (many dogs with kennel cough may also bring up white foam, which can be mistaken for vomiting).
Vomit that looks like white foam or foamy saliva instead of chunky or yellow vomit is often because of excess gas and air in the stomach. In most instances, your dog is throwing up white foam because there`s nothing much left in his stomach to eliminate.
Ginger is one of the best home remedies for your dog`s vomiting and upset stomach. You can make ginger tea by boiling fresh ginger root in water, cooling it, and giving it to your dog in small amounts throughout the day.
Treating acid reflux can be as simple as changing your dog`s food, or as major as surgery. Most veterinarians will recommend changing your dog`s diet to boiled chicken, rice, and/or blanched broccoli in order to sufficiently reduce the acid reflux. These meals should be given in small amounts throughout the day.
Causes of Dry Heaving In Dogs

Dogs can start dry heaving or retching for many reasons including: Upper respiratory infection. A foreign object caught in your dog`s throat. Kennel cough.

Kennel cough (also known as bordetella) is a highly contagious bacterial disease that can affect dogs, cats, and humans.
Some of the signs of parvovirus include lethargy; loss of appetite; abdominal pain and bloating; fever or low body temperature (hypothermia); vomiting; and severe, often bloody, diarrhea. Persistent vomiting and diarrhea can cause rapid dehydration, and damage to the intestines and immune system can cause septic shock.
Medicines to be given

Some of the medicines that are often given to the dog to control its vomiting are antiemetics and metoclopramide.

Honey can be a great home remedy for kennel cough as it can help soothe your dog`s throat and minimize coughing. You can give your dog 1/2 tablespoon to 1 tablespoon of honey mixed with a little warm water in a bowl. This can be offered up to three times a day depending on how often your dog is coughing.
In most cases, dogs will recover from kennel cough without treatment within three weeks. It can linger for anything up to six weeks.
Take away her food bowl and remove her water bowl, as well—guzzling too much H20 can irritate your pup`s GI tract even further. Instead, offer a few laps or ice cubes every few hours, suggests Elswick. “Gently rubbing his or her abdomen when your dog has an “upset tummy” may provide some comfort,” says Elswick.
Some recommended choices include Metoclopramide, Cerenia (for dogs), and Famotidine or Pepcid. Cerenia has the added benefit of helping dogs with nausea and vomiting from motion sickness. Natural homeopathic remedies that help with nausea and vomiting include Nux Vomica, arsenicum album, and pulsatilla.
Prognosis for a Dog with Acid Reflux

This can cause pain while swallowing, unwillingness to eat, and weight loss. If properly treated with dietary restriction and medications or surgery, if necessary, the reflux will decrease markedly and the dog`s esophagus will heal.

Acid reflux is the reverse-flow of stomach acid or intestinal fluids into the oesophagus (gullet) which causes painful inflammation of the mucosal lining.
The most common natural remedy for dogs with a kennel cough, or canine tracheobronchitis, is honey. Manuka honey, which is usually imported from New Zealand, is the most preferred type of honey.
Encourage Your Dog to Rest

Adequate rest is one of the best remedies for kennel cough. If your dog gets plenty of sleep, it will give his body a chance to fight the virus and recover properly. Put your dog in a room by himself, away from kids and other pets. This way, he will not be disturbed while trying to rest.

Is kennel cough dangerous or life-threatening? While a nuisance, kennel cough is not normally dangerous and is likely to need no treatment at all. But in puppies, elderly dogs or those with existing illnesses, the condition can be more serious and can develop into pneumonia.
The scent generally associated with parvo is caused by blood in the stool. Dogs with bloody stools because of hookworms have precisely the same smell. MORE IMPORTANTLY, if a puppy is diagnosed with Parvo BEFORE there is blood in the stool, the antivirals` effectiveness is MUCH GREATER.

Q. My black Lab is gagging and throwing up white foam constantly, what do I need to do?
ANSWER : A. You can try starving for 12 hours and then gradually reintroduce a bland diet such as chicken or white fish and rice. If the vomiting continues despite starving, vomits water, straining to pass faeces or is very lethargic then you should see your vet as soon as possible as I would be concerned about dehydration and electrolyte imbalances.

Q. My kitten has a very bloated stomach. Do I need to see a vet or do I buy a dewormer? we just found this kitten on the side of the road.
ANSWER : A. If it is a stray then you need to see your vet as soon as possible for a full examination. Yes you need a wormer but you need a good quality one from your vet, the over the counter ones are not as effective. You also need to treat for fleas and get vaccines. Your vet will be able to do all this and check that there aren’t any other medical problems that need attention.

Q. I have a male kitten..white body, orange sots on back and top of head. And one black spot on his tail. His mother is longhair calico. Is he Calico?
ANSWER : A. The Calico is a color classification rather than a breed of cat. Cats of any breed may be able to have a Calico coloration, however Domestic Shorthairs and Medium hairs (your typical house cat) are most likely. Coat color is also linked to a cat’s sex, so females are more likely to be Tortoiseshell while males more likely to be Calico. A Calico coat is one that is a white base with splotches of red, orange, brown and black over it. A Tortoiseshell coat is a black or brown base with white, orange and brown splotches mixed in!

Q. My cat is excessively scrstching herself., to the point she has sores. She is strictly an indoor cat. Did have flees been treated for 2 months
ANSWER : A. For every flea you see on your pet, there are 100 more in the environment. Get your pet on a good topical or oral flea control through your vet. In flea control, you get what you pay for. Consider asking your vet for a dose of Capstar. It helps get the problem under control by killing the fleas on the pet starting in five minutes but only lasts for 24 hours.

You need to treat your home environment. If you use a pest control service, tell them you are having a flea problem and they can adjust their treatment. Use a premise spray that also contains an IGR, insect growth regulator. This keeps eggs and larvae from maturing into adults and helps break the life cycle. Also, vacuum EVERY DAY, throwing out the bag or emptying the canister every time into an outside receptacle and spraying the contents with insecticide to kill the fleas you’ve vacuumed up.

Treat your yard too, since fleas are opportunistic and will hop a ride into your home on your pant leg without you knowing it. Concentrate on areas under bushes, in the shade. Fleas are less likely to be located in open sunny areas where it gets hot.

If chemicals are a problem, you can use borax. Sprinkle it into rugs, into corners and under furniture, use a broom to work it into the fibers and let it sit for hours, days even. It won’t hurt you or your pet to have it present. Then vacuum it up, reapply as needed. Food grade diatomaceous earth can be gotten from a health food store and worked into the rugs and corners in the same way as borax. These treatments aren’t as fast and effective as chemical insecticides but they can help.

You might want to consider boarding your pet for the day at your vet, to give you the opportunity to flea bomb your house without having to worry about your pet being exposed. They can bathe your pet and give a dose of Capstar while you treat your home.

Be patient, you may have to repeat these steps multiple times 10-14 days apart to help break the flea life cycle.

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.

Q. Is chocolate bad for my dog?
ANSWER : A. Yes chocolate is toxic to dogs. The higher the cocoa content the more toxic it is. Therefore, less amount of 80% dark chocolate needs to be consumed compared to white chocolate before toxic signs can be appreciated.

Also, the weight of the dog is important in terms of the amounts needed to be ingested before toxic symptoms appear. Less than 1oz of milk chocolate per 1lb of bodyweight needs to be eaten to be potentially lethal and less than 0.1oz per 1lb of baking chocolate is needed to be potentially fatal. If you are unsure, you should always contact your vet or emergency vet straight after ingestion.

If your dog has eaten more than the toxic amount, vomiting needs to be induced within two hours of ingestion. Clinical signs usually occur within 6-12 hours post ingestion. Mild signs can include increased thirst, restlessness, vomiting and diarrhea. More severe signs can include hyperactivity, increased urination, muscle tremors, unbalanced/uncoordinated, seizures, increased heart rate, increased breathing, coma and death.

Q. My dog threw up white foam stuff what causes that
ANSWER : A. White foamy vomitus is usually saliva and mucous that he has swallowed and it usually means his stomach was empty if he vomited. If he was coughing and gagged afterward, this could also explain the white foam. Watch him carefully, if he starts to feel bad, continues vomiting, loses his appetite, or develops diarrhea or fever, get him seen by your vet right away. He could have eaten something that disagreed with him, ingested some kind of foreign substance or toxin, may have been too active after drinking water, there are a number of possibilities.

Q. My 9 year old Lab has green discharge from eye, black diarrhea, hasn’t eaten in two days, and has blood red where the whites should be in her eyes
ANSWER : A. You need to see a vet asap black diarrhea can be a sign of bleeding in stomach. Not eating for that long will cause dehydration so will need to be rehydrated.

Q. We have been treating our 5 year old cat for black bumps that we treated with Special Diet. These bumps grow over his body
ANSWER : A. If your cat has black bumps or other skin lesions forming that have not cleared up with preventive flea treatment or changes in diet, it may be time to request some additional testing as needed. Your vet can take a skin scraping of one of the lesions and send it to a Lab for various tests. One test includes growing any bacteria or fungus present, and then subjecting them to various medications to find which one is best to use. Other tests just look for certain growth patterns to determine if a fungus or bacteria is present which can be treated with oral or topical medications from your vet.

Cats can commonly have chin acne, which is the formation of little bumps that can be red or black in color and may sometimes break open and ooze debris. The cause of this acne is unknown, however one theory is that cats can actually get bacterial infections from rubbing their chins on plastic food dishes or dishes that are not cleaned often. Treatment may involve anywhere from none at all in minor cases, to use of wipes, creams or antibiotics for helping clear up any infection.
