My roommate has a pomeranian that we have had for several months now. He was rescued from a neglectful home. When we first brought him home he weighed 9 pounds, according to his size he should weigh probably 10 or 11 pounds. He will not eat his kibble, only like a mouthful a day and is losing a bit of weight. We have tried all different brands of dry food as well as wet food, mixing them together, adding vitamins, fish oil, and adding water. He DOES however eat treats, cat and dog poop, anything in the trash, stuffed animals, underwear, etc. He has his own space to eat away from the other dogs, so I don't see that as being a problem. Does anyone know if this is a sign of illness or just pickiness? Are there any suggestions on what else we can try? My roommate really does not want to take him to the vet but I am getting very very worried!
