I need to ask and I know it’s early days yet with my BT cross but do Border Ts whistle & whine is this sort of normal? Never had a Border before, looked after my cousins for a week or so but he is old, deaf & a bit crotchety! I suppose in time the ‘singing’ will ease off, at the moment she ‘sings’ for her supper, if one of us is out of sight-I know, anxiety-& in the car-probably anxiety again-and any time in between really! I bought her a composite ‘bone’ for in the car and that seemed to help, until it disappeared under my seat! She is learning a lot and is a lot quieter on walks that she already knows, a new walk is a bit frantic, she needs to see all of it instantly! She can learn and does so quite quickly but tends to ‘forget’ just as quickly! I can see her staying on her leash for quite a while yet!
