My dog chewed on something while lying on a throw rug with fringe and an x-ray showed there was string wrapped around her intestines. It could have killed her! Thankfully, she was in the hospital in time.
(Please skip "A" with puppies, a dachshund or any dog with the body shape of a dachshund and toy dogs due to their fragile spines. It would be best to talk to your Veterinarian if you're unsure if you should use "A" on your pet.)
If this can save just one dog, I'll be happy!
