Honestly, I am not for chaining dogs irresponsibly
(I.e with no shelter, no water, no food, being out there 24/7, etc.).. but some breeds like Northern breeds and terriers, sometimes it's the ONLY way you can keep the dog in the yard and keep it safe.

I had to tie out my Jenny girl (RIP) when we lived at our old house because we didn't have a yard. Not every dog that is chained is being neglected like some people think.

Sometimes it's the only way you can safely confine your dog, even if you are out there with them what if they see a cat or another dog and go balistic?

It keeps those animals safe, too as long as you have a proper chain set-up I see no problem with it.

You cannot say every dog that is being chained is being neglected, there are a lot of people that chain their dogs to keep them safe and people who chain their dogs that have dog aggressive dogs if they want more than one of that breed, it's called being responsible and not neglecting your dog.

So I don't agree with anti-tethering laws, personally because it brings a lot of trouble to people who are innocent and only properly containing their dogs and that have adequate shelter.
(Think of the H$U$ who are out to get people who have a yard full of dogs and think they are fighting them, when they are not.)

The ones who think their dogs are being neglected, they get taken away and possibly even killed for nothing! I do not chain my dogs, but I would tie them out if that was the only way for to keep them in the yard and safe and I would be pissed if someone ratted on me when they don't know the situation.
