What time(s) did your dog throw up the yellow bile? Was it in the morning...or before your dog's first meal? Does it happen often or is this the first time your dog has thrown up yellow bile?
If so, it could be that your dog's stomach was empty and thus a bit irritated. Sometimes dogs will chomp on grass to sooth their stomachs, and then puke. My dogs all do it occasionally.
I generally do not worry unless it is happening frequently---or there are other worrisome signs, like refusing to eating or drink, poop issues, lethargy etc.
For me, I would not
rush to a vet on a weekend if my regular vet was closed. I would watch my dog's behavior and judge it from there. If the vomiting continues or increases then I would probably go to a vet. Or if my dog flat out refuses food, then I would worry!
But----I am a minimalist when it comes to running to the vet every time something seems off. That is just me, please use your own judgement to what feels comfortable to you!!
Some people suggest that if your dog is puking this yellow foam or bile in the morning, give the dog a small snack or biscuit right before bedtime so that the dog's stomach is not completely empty.
Here is part
of an online article about vomiting yellow stuff (bile) that may help you decide to go to the vet (or not) this weekend. Hope it helps...worrying about going to the vet or not can be so stressful, right??
**************** Why Does My Dog... Vomit Yellow Foam?
BY DR. MARY FULLER DVM In most cases, yellow foam indicates that the dog's stomach is relatively empty of food.
The yellow color comes from bile, a digestive fluid that's produced in the liver, stored in the gall bladder and then released into the small intestine just below the stomach.
A dog may vomit yellow foam simply because his stomach is empty and the bile can be irritating. If your dog is otherwise healthy — and he's eating and defecating normally — it may help to reduce the time in between meals. But this doesn’t mean that your dog should be fed more. Instead, one meal can be divided into two or three smaller but more frequent feedings.
Unfortunately, there are many medical conditions that can cause a dog to vomit on an empty stomach, so a phone call to your vet is a good idea if you notice this problem. http://www.vetstreet.com/our-pet-exp...it-yellow-foam Why Is My Dog Throwing Up Yellow Foam?
