Re: OMG!!!! My dog just bit the mailman!
Vike...I realize this in NO way, pertains to you..but I was raised with all hunting dogs and they were considered "tools." I know yours is a "family member (to the others)...but I hate to say it...when they start to attack people for no reason, it doesn't stop without severe intervention. Most would consider it "cruelty to animals" and have you charged...so I wouldn't even suggest you hand the dog's ass to itself.
With our dogs, they were kept in a heated/insulated Kennel and outside all year. When the time came they could no longer hunt, they were taken out back and put down.
I fear that you are going to have to do the same with this one...just with the vet.
