Honey- I need more info. When are these bites occuring? What are you doing? ( like- making this up the dog tries to bite when I try to put on a leash, or if the dog is eating etc). Also- which breed is dominant in the lurcher? ( for anyone else reading this- its a mixture of sighthound and herding breed usually..) Is there a consitancy.. Like one using the leash example- the dog is fine with the lead- then next time no. And how is the dog with strangers? Do the bites occur in the house or out etc etc etc.
