Thank you all for your responses. We are in St. Charles, IL which is the western suburbs of Chicago. If anyone does know of someone we can call, we would really appreciate it. Otis was neutured at around 6 months of age. My son got him as a puppy and did the training with him. He was very responsive with him, and learned many tricks. My son did not take him out too much, except over here, but we would go to the dog park and although Otis was always very eager to get to other dogs, he would never bite. I really hadn't thought about the invisible fence and how that could be affecting him. Any other thoughts, or people to contact would greatly be appreciated. He is not agressive at all at home, and our other dog can really be aggravating and he does nothing about it. Please Help!!!

Our Basenji Otis is 3 1/2 years old. He is my son's dog but has been living with us for the past 9 months. We also have a 3 1/2 year old lab/terrior mix. Lateley when I walk Otis, he is very very confrontational with other dogs. We also have an invisible fence and is confrontational with other dogs when they pass the house. When on a lease, he gets very jumpy, trying to get at the other dog, and my husband and I have both gotten bitten during these encounters. He was always fine at the dog park as long as he wasn't on a lease, but last time we went to the dog park, he went up to greet another dog with his teeth chomping and the dog ended up needing 12 stitches. As I am new to this forum, I believe I have come accross some good information, and I know that I need to work with him to overcome this. It has really gotten out of control and expensive!! My question is, what kind of a muzzle is best to use on a Basenji. I bought a soft one online but it is too big as it goes right up to his eyes. I need something asap so I can take him out on walks and still work with him. Thanks so much.
