My son’s friends have had a border collie for eighteen months. The dog is unhappy and has been put on antidepressants. The dog is stuck in a small house with a tiny garden and, because it shows ‘concerning’ behaviour ( aggressive … nippy…has nipped a man … hyperactive…) my friend and her partner are going to speak to the vet tomorrow about putting it to sleep. The dog walks daily on a lead. Sleeps in a cage at night. I am so upset … what would you do? My son is begging her not to euthanise the dog. He wants to phone shelters tomorrow. Shelters take Bullies - surely they would take a border collie?
