Please use a harness if you are tying your dog up.
I know that everyone is entitled to raise their animals how they see fit but it really bothers me when I am looking at pet pictures and I see dogs tied up outside. We put our dog on a long lead when we are outside with her and obviously if someone is taking the picture they are outside with them too but please people attach the lead to a harness instead of a collar. It is so much safer for the dog. I know they should be "ok" if someone is outside with them but they could still run to the end of the lead and hurt their necks. I just think it is such an easy way to prevent injury so why not just do it.
