I too have a 7 year old feline named Buddy and when Tessa (our boxer baby) came into our lives, Buddy couldn't stand it!! HE would chase Tessa!! hissing and clawing (very scary), but when Tessa started to run, she ran right for Buddy - I guess she felt she owed him! Now the two have an understanding that we (my boyfriend and I) don't get involved in. If Tessa gets too annoying for Buddy he'll retaliate and Tessa knows he's had enough. Buddy also has a safe place in the house too, so when Tessa is too out-of-control Buddy just hides from her. I think as long as the cats tail is wagin' that the cat is happy, and as long as the dog knows its limitations then dogs and cats can get along and live happily with one another.
btw cute pics! I love brindles! Good luck with all the training. My only advice and my only regret is that I didn't teach her early enough not to jump up on people. I thought it was really cute when she was small, but now that she's so big it's really annoying when she knocks my company down to the ground. I'm working on this problem, but it's going to be a loooong learning process
good luck and welcome,
Tessa's mum Tammy
