Get Your Dog Care Questions Answered by Experts
Hello and thank you for requesting me.
Can you tell me if your pup has eaten any non food items such as bones, raw hides, toys, etc.?
How long has this been going on?
Has the pup eaten any human food that you know of?
Have you changed the dogs food?
what color are the dogs gums?
When was the last time the dog ate?
What type of treats do you give the dog?
He may be having a reaction to something he ate. It also sounds like irritation in the stomach such as bile which would be the yellow.
If you have it, try giving the dog a pepcid AC. Don't feed the dog anything else tonight but do allow water. Tomorrow night start a bland diet of boiled chicken (white meat, no grease, no fat) and cooked white rice. Between fasting the dog for 24 hours and starting a bland diet it will give the intestines time to become less inflamed.
Watch the dog's vital signs and I will direct you to a link that goes over how to do that.
