I am about to put down my lovely blueheeler cassie this sunday:( . I have come to terms with this but I do not know how my other dog, pepper, a little jack russel terrier cross, will cope. She is younger than cassie and has known and depended on her for as long as she can remember. In the few hours cassie was at the vet today pepper singlehandedly destroyed the fly wire on the back door! If anyone has any tips on how to combat loneliness in dogs, I would love to hear from u. :)
