When I was a kid, we had two tortoises with 2 dogs
TBH I don't remember any problems with them, I think the dogs used to think the tortoises where rocks, that slowly moved
They did however take a keen interest in our hedgehog, they never learnt that you get your nose spiked if you sniff them
Wow 50 years old though, how long do they live for?
Just noticed I think this thread is in the wrong place, i'm sure someone will move it for you
