Aggressive on Leash 4 Year Old Jack Russell
I have a 4 year old Jack Russell that is extremely aggressive when he sees another dog while we are walking. He will attempt to get to the other dog and attempts to bite his leash, whoever is walking him or our other dog to in frustration at not being able to get to the other dog! He has even bitten a shrub!
What is the best approach? We've tried stopping and letting the other dogs pass. We cross to the other side of the street to keep our distance. We thought just walking him twice daily that it would desensitize him to it all and it would cause such terrible behavior but that is not the case.
