We've had similar problems with our two. Rocky is a little worse though, especially if we see a cat or another dog. We've tried all kinds of things but have yet to completely solve the problem. Let me know if you come up with anything!
What I've found more successful than citronella collars (I don't like spraying the stuff in my dog's face) is a similar collar called an AirJet collar. It works on the same principle but spurts air instead of citronella. I haven't had the need for one but along with a good training program I know many people who have had great success with itOriginally Posted By: DaisyTheDevilDogOnce again, I highly recommend a Citronella collar. Look for my post in the the topic called 'Leash Aggression' for more info, or just click on my user ID to the left and then click View Posts. It really works!
Oh, sorry, terrible wording - I know it doesn't spray it directly in the dogs face, but I don't like putting it that close to them especially with a beagle's heightened sense of smell. I also don't like the citronella getting on their coatOriginally Posted By: DaisyTheDevilDogThe citronella collar doesn't spray in the dog's face, it is angled away so it sprays in front of the dog. click for photo
Most dogs will jump back when it goes off, so it's not like they're running into the small bit of spray that comes out anyway.
That being said, the air collar sounds great and effective too!
