njon, but if your child falls into the tanks they could drown so not even fish are safe!

Reet, tough call Any dog has the capability to turn. We have a greyhound and while they are placid many have been bred to chase and have been blooded for racing. They also have strong jaws (not as strong as pitbulls but the ability to cause massive damage). Our greyhound was savaged by another greyhound and it was hideous. My children will never go near that other dog and I am vigilant with them around Benny even though he has never shown signs of aggression. We knew this other dog and she just snapped - it was so scary!

You need to consider with your dog, the likelihood of the breed suddenly snapping at an incident changing from sweet to aggressive, your ability to control him, the general temperament of the breed, the strength of the dog and the damage that could be inflicted if he did snap. I guess a chihuahua suddenly turning and attacking is not going to inflict the same damage as a Husky but if the breed was renowned for aggression I still would be concerned.
