Lots of dogs every day attend vet hospitals with muscle tendon and joint issues
and also with neck injuries.
A roo jumped out on us on our walk this morning and if my dog had been just on a collar she would have strangled herself (they are very
exciting) I had been reading this debate earlier and was thinking about maybe trying just her collar instead of her harness but am very glad i didn't.
Everything has a good and bad side, all equipment (even a collar and lead) is restricting. You just need to make your decision, buy the best quality you can and go with it.
in my opinion :)
