Ours must be the exception, severe hip dysplasia at 6 months plus urinary incontinence (pre speying, so not caused by that. )
Borders are generally very healthy but thank goodness ours was insured.....no hip scores available when we bought as they aren't done normally for borders cos they don't normally have hip problems...:-(
Vets wanted to chop both hip joints off but we went for hydrotherapy and MSM/glucosamine tablets and that made such a difference when re x rayed (muscle now supporting the joint where bone should be) that we decided not to go ahead. Taggie is now 9 and hasn't been lame since, although it has stopped us doing the long walks we had planned with her, we stick to short ones.
