hey guys, im not sure if this is the right place to post this or not. first i have to say izabella is the best dog in the world! almost 11 months, so amazingly loving and sweet and so tiny at 18-20lbs. well she is tiny to me lol. im curious about what is the largest size sheltie anyone has ever seen? im having some issues with the rescue blue merle charley, i posted before on him. i no longer talk with the previous owner as she keeps upsetting me, but anyway, i measured charleys top of head down to is paw and he measures 23" tall, a month ago he weighed in at 40lbs, i havent weighed him recently. my vet says collie, collie rescue says border collie mix (NOT). i love him regardless but he has some issues, seperation anxiety is one of them. stealing food off of my counters is another. other than that i have really turned this dog around. he listens so well, except with this jumping up on my very high counters and stealing food, now izzy cant do get up that high. she measures 14" from head to floor. i just want to be able to work with my dog, and in working with him, since collies are not shelties, they are similar, but not the same breed, i want to research, just like anyone should to work with a rescue dog. thanks guys!
