Hello- I have several other questions for all you Rough Collie owners out there. Our Collie Pup is 16 weeks and since we got her at 8 weeks she yips a lot. We keep her confined to the kitchen when we are not at home or when we can't watch her completely (she has been chewing the dining chairs). She yips out of the blue for no apparent reason. She is never alone and always has the company of our older dog and our cat. Are Rough Collies just inherent yippers? We take her for long walks 2x's a day and play with her with toys quite often. I hope you all don't mind all of the questions but we are new to the Collie world. I can read things on the internet but I really prefer true life experience. Thank you so much.
