I have a Pom-Chi who is around 8 years old (but doesn’t know or act like he is) and has a HUGE attitude, lol. Seriously, he wants to eat everyone he sees outside. I believe that he only tolerates me and my girlfriend because we feed and take care of him. lol All kidding aside (but he really does have a huge attitude) is there any OTC medicine I can give him for an upset stomach? I remember the last time I took him to the vet, he said I could give him OTC Benedryl for his allergies/scratching. Just curious.
