"Loud" behavior at the dog park?
We have two lovely dogs, an 8.4-pound Poodle/Schnauzer mix (Browser) and a 22-pound Westie/Schnauzer mix (Wall-E), both adopted from local shelters. They are the best of buddies and both very well behaved. The Westie is actually going through therapy dog training and is excelling...when he's wearing his vest and his sister isn't around.
We regularly go to the dog park and Wall-E regularly chases dogs away from Browser. She's not a huge fan of getting her rear sniffed by large dogs (but I've decided she needs to suck it up and take her to the park anyway) and she shows her teeth or squeals at them to get them away from her. Wall-E then comes rushing in and chases the dog(s) away from Browser and is completely relentless. He never puts his teeth on the dogs, but he's just so LOUD! He seems completely ferocious, even though the dogs don't even come away with his slobber on them.
He's a naturally "talkative" dog at home, regularly growling or grumbling at us when we get him worked up. I really don't want to resort to an anti-bark collar, but this behavior is really starting to annoy me. I'm tired of having to follow him around, verbally correct him, and then apologize to about a dozen dog owners.
Other than this small issue, our pups are great, so I don't really know what to do about this particular problem. Wall-E will come when called, sit, stay, walks off-leash when on my college campus (well away from roads, of course), and does everything else I could possibly ask of him.
Is there anyway to control his "voice" without using a collar?
