I've been raising my 11 year old Yorkie "Toy" since 5 weeks of age and he vomited in the beginning all the time when he rode in the car with me. It's because they're scared and I found that if i confined him in a small space like a carrier bag or a small kennel, he felt better about it and eventually grew out of it.
I just picked up my new baby girl "Gia" last week from LAX to Phoenix and we only gave her "mother's milk" as precaution, and she did not vomit. She did however do that after we drove her home from the vet, but she was given an antibiotic shot due to a cold, so I think that's why she did that. Plus, the heat, the stress at the vet probably caused that. It's quite stressful for a dog to travel, until they get used to it!
My breeder also told me to give her Eukanuba small breed puppy. She hated it and only ate a half of spoonful at a time. She's only barely a pound and a half, but I thought she should eat more. Si I looked into home cooking for both of them and surprises, surprise, she gobbles up all of her food, One good tablespoon each feeding, 4 times a day.
She also chews on grass and leafs and twigs. That's just a puppy thing, getting to know their new home I guess. You mentioned he peed while drinking. Was his water too cold?
I have some great recipes and upset stomach remedies. All natural based, if you're interested, PM me and I'll be more than happy to share those!
For the meantime though. If he doesn't eat, make sure to give him Nutri-Cal!
Good luck and congratulations on your new baby!
