Since I am one of the few I am sure who insures my 2 APBT, there are 2 recomended companies in Ohio, if you call Animal Control. There is a place in Lancaster that does it, and for my 2 dogs it is $600/ 6 months, or 1k/12 Months.
The decisions on if your dog is a "Pit Bull" is completely up to the Animal Control Officer. If they say it is a "Pit Bull", and it resembles a "Pit Bull" then you get charged for no insurance. As well the judge who does these cases, is a tool. If you show up twice to his court for the same thing, he will take your dog, and have it put down. Saw it happen while I was there, for my failure to insure a "vicious dog".
As well Good Canine Cert, doesn't get around the state law in Ohio. I asked about that since my Males are already 5x Registered. The Animal Control officer, stated there was no way around the Ohio Law.
