There is probably nothing to worry about but you should immediately seek medical advice from your vet to find out what the situation is. Your dog should be fine as this could just be something they've eaten coming back up. Try to remember what it has eaten. Ensure the dog is well hydrated and lay your pet down somewhere soft. Make sure your dog is still able to walk around a little bit and do not under any circumstances feed it anything.
There could be a number of different reasons for the foam including things such as ingesting something toxic, an obstruction somewhere, or even bloating or an allergic reaction to something in its food. It could also be grass as dogs like to chew grass much like cows. It is not uncommon for dogs to swallow grass as it makes them vomit - a defence mechanism should they feel they have eaten something bad.
The best course of action is to keep your dog warm, hydrated and comfortable, and to call a vet immediately. There aren't many major problems that come from vomiting stomach bile, but it will soften her throat, and if your dog does vomit a lot it could lead to burning of the oesophagus. It is probably some sort of intolerance to food but if in any doubt make sure your dog is well looked after and make an appointment to see the vet.
The dogs vomit being white foam, I believe its their stomach acid. My Pup dose that in the mornings sometimes before feeding. Or when she is to excited. Its not a bad thing unless you see blood or happens frequently. Then Visit you local vet .
You have not mentioned about foods and feeding habits of your dog because foamy mucus vomiting in dogs can be due to food and feeding habits. All those foods which cause irritations in the digestive tract can cause bile or unproductive vomiting.
Feeding habits like overeating and eating quickly can cause this conditions. Dry foods are also blamed for mucus in the vomiting. Some conditions like stress, nervousness and canine bloat can also cause unproductive vomiting. In my opinion, if foamy mucus vomiting is permanent feature in your dog then get advice from your local vet.
There are many causes of vomiting in dogs. Common causes include dietary indiscretion,
toxicity, foreign body obstruction, infectious diseases, kidney problems, liver
disease, and pancreatitis. If your dog
vomits for more than 12 hours it needs to be examined by a veterinarian. Withhold food and water for 6-8 hours to
allow the stomach to settle down. If
there has been no vomiting slowly reintroduce small amounts of water, then
food--feed a bland diet like boiled chicken and rice.
You should withhold all food for 24 hours. Make sure plenty of clean fresh water is available as vomiting can rapidly cause dehydration. If your animal is showing signs of illness like lethargy, depression or fever, or the vomiting is severe or very frequent you should take him or her to the vet. After 24 hours feed a low-fat easily digestible meal like cooked chicken and rice. If all goes well you may reintroduce the normal diet over the next couple of days. If the vomiting persists you will have to contact your vet.
It could be a lot of things, those are more universal and general symptoms that indicate you need to see a vet. It could be anything from a bacterial or viral infection like parvo, parasites, poisoning, blockage or other things. It may even indicate bloat but you don't have much time to get to a vet in that situation, bloat can kill in a matter of hours.
You need to see your vet and they will have a better idea of what may be the problem and what needs to or can be done after an exam and discussing everything with you. I hope your baby is feeling better soon.
If your dog is vomiting white foam occasionally then he is not sick. Only persistent white foamy vomiting is problem. This condition can be due canine bloat which is medical emergency and is usually related with foods and eating habits of the dog. If your dogs is vomiting white foam since last 24 hours then take him to vet for diagnosis and advice.
Dogs will eat grasses because they feel queasy, and they will throw up because they've eaten grass. My dog throws up foamy white stuff if his blood sugar is low, also when he licked the toad (glad my dog isn't the only goofball!) and sometimes when he gets excited and overheated. It really isn't much to be concerned about if it is the only real symptom. If he gets shaky, lethargic, feverish, wont eat or drink, or can't hold food or drink down then take him to the vet. Otherwise you can probably take a wait and see approach. Mine has been doing this for maybe four years, and he's just fine, even the vet couldn't really explain why he does it.
