Silke, you have Boston terriers too! I have 2 too!!!
1 male 4 1/2 years (Bobby) and 1 female 11 months (Mathilda). They are quite the little dogs and have a whole bunch of energy especially my little young one, boy she drives my other 2 dogs nuts!!! I have a retired greyhound as well and he just watches them and grunts when they are too much for him! Quite the funny little buggers, my Bobby still doesn't get that he's a dog and not a human!!!
Keeper of 5 snakes, leopard geckos, 1 green iguana, 20+ tarantulas, 2 dogs & a bunch of rats!
