How to manage my dog's reactivity and barking at other dogs on walks?
Thanks for using Petco Pet Education Center, formerly Petcoach. The answer is complicated and stems from the root of the problem. If Cassidy genuinely wants to play and meet these dogs, I don’t know that I would necessarily do anything.
If this stems from fear of other dogs, leash anxiety specifically, or protectiveness of you, these are treated differently.
Lowering the fear threshhold (if appropriate) via anti-anxiety medication can help tremendously. I’ve had severely dog-aggressive dogs who, with medication, don’t seem to care at all when they pass another dog on a walk. Results of course vary depending on root cause, medication, and individual dog.
Counter-conditioning is also crucial. This is the act of training Cassidy to associate other dogs with something good (usually treats). This can take weeks and all of dedication and patience but is usually more effective and long-lasting than medication. Sometimes it is not effective however, until the medication is started.
I’d have a conversation with a vet first to help narrow down the cause and start on medication if appropriate. Then move to a reputable trainer or behaviorist.
Best wishes to you and Cassidy!
