Hello I recently helped rescue a Greyhound cross. We think she has redheeler in her but there may be pittbull as well. She is dog reactive and any advice I can get to help with this would be wonderful. She is a spayed female 5or 6 years old now. She did have a litter of 10 pups 4 years ago. She is great with my pack (4 jack russells and a petite bassett griffon vendeen), but reacts to new dogs. She grabs and shakes them, and as a result is muzzled while out, this makes her a useless hunting dog. I feel she would make the perfect addition to my current working pack, if we could just lose
