Re: Mik: 13 yr old Shih-Tzu
Theophylline was another drug we tried but Chris couldn't tolerate - it increased his already fast heart rate.
I suspect that the PDA he had as a puppy not being repaired for so long damaged Chris' heart when he was young. He wound up at a city pound and we adopted him at about 5-6 months. At first a lot of his weakness was attributed to his being so thin and having so many parasites - fleas, worms, ticks plus kennel cough... once he recovered from most of that, they found the PDA.
He didn't have surgery until he was about 8 months old. At that point, he was so weak from lack of oxygen that we weren't sure he would survivie long enough to have the surgery or survive the surgery. But he did and was like a new dog once that closed up that hole! He felt good, probably for the first time in his life.
He never had much stamina. Some of the cardiac issues were noted back in 2004 when he went to the vet school about his diabetes. But they didn't become pronounced for another year or two.
That's a good question about the Keflex.
