12 year old getting aggresive
our 12 year old jack russel dog has been diagnosed in the last year with colitis. we have managed the condition with a change in his diet but he sometimes has the odd bout. But he seems to be more aggresive in that if he doesnt want to go out he will nip us if we try to pick him up or put his lead on him. My husband has two bites this morning, one on each arm, no blood but bruised. He has now put him in the garden and says he will stay there all day, but i know he suffers in the cold these days.
