Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Alex!

I would worry if Alex is able to hold down liquids but not solids. If this has been going on since you have had him then I would worry about a congenital defect causing constriction of the esophagus (PDA=patent ductus arterosis). if this is a new thing it could be intestinal parasites, viral or bacterial infections (especially parvo), food intolerance/allergy, or foreign body obstruction. I do not recommend human dairy products in animals as they are lactose intolerance. It is also not nutritionally appropriate for a 4 month large breed dog. I would try canned dog food or wet dry dog food in a mush. See if he can hod that down. If he can not he needs to see a Veterinarian for a work up. We are not legally allowed to diagnose and prescribe drugs over the internet as we can't examine the pet which is required to prescribe drugs.

I wish you and Alex the best!
