Hi thank you for the question.
I just have a few questions
What food does he normally eat
Has he eaten anything he should not , plants, etc
Any change in his diet?
ok, it seems he just may have an upset tummy.
I would not give milk as that can cause diarrhea.the other treats are fine.
For today and tomorrow I would put him on a bland diet of boiled chicken and rice making sure to wash all fat off of the chicken after boiling.
I would also recommand trying to add some dry kibble into his normal diet only eating can is not good for their teeth, the dry kibble helps to clean them.
Purina one is a good quality dry that can be purchased at the grocery store.
If you have pepcid ( generic is famodine and really inexpensive)he can have 1/4 tablet to help lower the acid in his tummy tonight, if you do not have that he can have a teaspoon of pepto
Please let me know how he is doing tomorrow
