i have a 1-year old lhasa apso who has started growling and snarling at us (my family). it started a week ago, when i gave him a greenie (treat). my mom went to pet him and he growled and snarled and tried to bite her. he has never done that before and is a very nice, calm dog. then yesterday my sister went to pick up his water dish to fill it up while he was eating (the dishes are right next to each other) and the same thing happened. this morning, i went to pick him up (he was not eating or anything, just lying down), and he growled and snapped at me. this is very unusual for him, he is usually very submissive. i got him from the pet store where i worked when he was 5 1/2 months old. i got him for free because he had just recovered from pneumonia. he was still on anti-biotics when i got him, but he was pronounced better by the store's vet. about a month ago, i got him neutered, and my vet noticed he was coughing again, so she did a chest x-ray, and discovered he has pneumonia again. now he is on anti-biotics again, and i am wondering if maybe he is in pain and that is why he is becoming aggressive? also, i have a cat that likes to bully him and eat my dog's food, and maybe that is why he growled when we went near his food? i have never had aggression problems with any of my other dogs and i don't know what to do. any advice would be appreciated. thanks!!!
thank you for the advice, i think the first thing i'm going to do is take him to the vet, this is really uncharacteristic of him. and he's been randomly barking and whining, which is also weird for him. he usually never barks, unless he needs to go out. so yeah...hopefully nothing is seriously wrong...i'm just worried that h's become immune to anti-biotics, since he's been on and off them since he was 4 months. i don't know what else they can do for him.
Sounds like he's not well, I am cranky too when I don't feel well! It's good that he's growling, because he's warning you! Get to the vet and once he's feeling better start some obedience training and I always suggest doing the NILIF method (you can search that on the web)
