We are renting with our 2 dogs and 2 birds. We are very clean with our dogs, they are bathed regularly and do not have fleas. Even though they were previously indoor dogs we now keep them outside as we aren't allowed them inside and don't want to do the wrong thing. I understand there are gross ferals who would let their animals run wild in rentals however it really ruins it for the good pet owners. If we were allowed our dogs inside we would definitely leave it in the same condition as when we moved in.
It's so sad seeing how many dogs are surrendered because families can not find houses to allow their pets. We would be happy to pay an extra pet bond to keep them inside. However while they would prefer to be in with us they have really adapted well to the change of being outside.
