The owner of the leashed dog is liable. If the dog that is on its own property is attacked, the owner should pay for the "home" dog's care. The owner of the leashed dog is still responsible for its behavior.
The owner of the cat & possibly you if you &/or your dog were trespassing on the owner's property or if your dog was not on a leash.
No it is always the owners responsibility, if they fail to control their animal they are held liable.
I would say, that you should keep your dog on a leash if he is going around humping things. In a change of state, its the other dogs fault. GOOGLE IT!!!
You could be and the answer to that depends on the leash laws in your area. Call animal control to find out.
probably the person with the off leash dog
It depends, Was the dog on your property? Did the dog show any aggression towards you, or your dog? And was the other dog on a leash?
Yes, if your dog was on leash or on your property and another dog came attacked your dog then the dog's owner should be responsible for all vet bills.
If the other dog was off leash, then probably not.
A dog lead is another word for a leash.
one is a leash one more is a tether another is hobble
tether (doing the crossword are we?)
Sure, with the proper training. Be aware, however, that even if a dog is trained to walk off leash local laws and ordinances may require that they be leashed when off the owner's property.
