Thought it best to join these forums as we have a strange problem with our dog Rosie , a Lab cross. She is 7 years old, and up till earlspring last year has given us no problems. But now we have dificulty in getting her to go any distance if we have a nice day with a clear blue sky ! Last year she was `spooked ` by a hot air balloon overhead while we were out walking , she then found her own way home ! When out now she sometimes sits and refuses to procceed. This then entails me having to pull her. We have fitted a head harness, but this seems rather cruel , We would be grateful for any advice that may be forthcoming as this must be a very unusual complaint, Derek.
