Hi all! Our vizsla Memphis has always had issues with separation and storm anxiety, but in recent months he’s begun to show aggression towards my husband and I when we try to crate him or leash him for a walk. He growls, refuses to follow commands, and has nipped us both on multiple occasions without drawing blood. He has even lashed out at our dog walker. He doesn’t do this everyday and we haven’t been able to identify triggers of when a typical day of good behavior might turn sour. He was a rescue and while we don’t know his exact age, we can estimate that he’s around 10 or 13. I’ve been his care taker for about 10 years and he’s always been sweet and happy, so this new behavior is surprising and upsetting. It’s as if he becomes a different dog for a moment. We continue to be gentle, but firm with him until he cooperates, but it can often be a scary situation. Has anyone else experienced their senior Vizsla becoming aggressive? I appreciate any advice for how we might cure these behavioral issues so that we are able to trust him around his dog walker!
