Hi April, I'm no expert on genetics but I'm certain that having prick ears or flop ears is definitly an inheritable trait. My reasoning behind this statement is that some breeds have all prick ears and some are all flop eareed. So somewhere along the line someone bred for that quality in that breed. Since the Border Collie isn't and shouldn't be bred for qualities such as ear stance or color, it's a random thing in the breed. It may very well be passed by male BC's in certain (or all) bloodlines. I don't know the answer to that. I would guess that it's a throwback to some type of dog used to create the BC. Have a good one!

Hi Bill and Pam, Thanks for the response, I'll use another product for my BC pup. No point in taking the chance. Actually Pam, I lost Kevin's number. Suppose I could beg..sweet talk...cajole you into sending it to me again??? Thanks again

HI, I've used Ziemectin (main ingredient Ivermectin) for years on my dogs (non BC'S) and never had any problems with it. I saw the post here on reactions to Ivermectin by BC's. Have I missed something? Do BC's have an unusual intolerance for Ivermectin? I haven't used it on my pup yet due to his age but I don't want to cause a problem if the breed is predisposed to problems from Ivermectin. Thanks
