WHAT DOES A DOG FOAMING AT THE MOUTH LOOK LIKE?

Foaming at the mouth is the common term given to excessive, frothy drooling. Foamy drool often takes on a thick, whitish appearance and is different from more typical drool which is thin and clear. 

Some dogs may foam at the mouth as a result of overactivity. If your dog has just been playing and has been more active than usual, there is probably nothing wrong with them even if they are foaming at the mouth a bit.

However, if your dog has not recently been active or if they are exhibiting any other strange or concerning symptoms, the foaming at the mouth could be a sign of a more serious issue.

WHAT CAN I DO TO HELP MY DOG FROM FOAMING AT THE MOUTH?

Call the vet right away if you are concerned that your dog’s foaming at the mouth may be due to something serious. Identifying the reason for this behavior will be key in making sure the proper care is given.

Veterinarians can perform a physical examination and certain tests to try and diagnose the cause for your dog’s signs, then offer solutions and options to help them recover whenever possible.

Treatment options for foaming at the mouth will vary depending on the cause of the condition:

Ingestion of something toxic or dog has heat stroke

If your dog has ingested a toxin or is suffering from heatstroke, they need to go to the emergency vet immediately. The sooner you take your pet to the emergency vet, the more likely they will be able to make a full recovery from this condition.

Ingestion of something foul tasting

This is usually self-limiting and will resolve on its own as the taste fades. If your dog’s signs don’t resolve quickly or worsen, please seek emergency veterinary care.

If Dog Has Dental Disease

If you suspect that your dog’s dental disease is the cause of their signs, go to your dog’s primary care vet as soon as possible. Your veterinarian may recommend dental cleaning and/or even removal of the damaged teeth, depending on the severity of your dog’s condition.

Dog is Nauseous or Having Seizures

If your dog is feeling nauseated or is having seizures, consider the situation.

Is the nausea coming from a known issue, like a new medication or a change in their food? If so, you may be able to start by monitoring at home and see if it resolves. If it continues or worsens, they should be seen by a veterinarian.

Are the seizures new, or is this a known condition? If it is known, you can probably also wait—unless the seizures are long, frequent or associated with a change in behavior or other signs of illness.
