Does someone have a good link to a website that I can read about the damage using a dog collar can give the dog??
Almost everyone where I live uses a dog collar on all sizes of dogs, even uses flexi with collars and I've seen many people that just let the dog run and run then he chokes when he comes to the end of the flexi lead ! so sad.
I need some good links to educate those people.
Im started to use the harness always, but still I have a collar for him inside and when he's tied outside I use his collar couse he otherwise takes himself out of the harness if he for example sees a cat, I'm always with him when he's outside tied and I watch out for cats

If we see a cat or other exiting things I bring him inside so he doesnt choke on the collar.
