My dog is vomiting yellow, tired, and not eating. What's wrong?

Pet's info: Dog | Mixed Breed | Male | unneutered | 1 year old

My 1 year old mixed breed dog was sick 6 times yesterday. The last 3 times were a thick yellow colour. He ate some grass on his walk too.. he only ate very little yesterday and seems to be tired and not very energetic which is very out of character for him.

Hi, and thanks for your question. As a first approach, I would suggest to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, more vomiting, lethargy or inappetence. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
