Of my 5 greyhounds, 3 responded to a squaker - they would come running and I'd give them a treat. We'd do this once in awhile with the hope that if they ever got away, they'd come back to a squaker. They responded immediately but didn't go nuts. My 4th greyhound doesn't respond at all and my 5th one GOES CRAZY! We got Rumor in January and today I got the squaker out to see if she'd respond and maybe work on some recall. She came running, wasn't the slightest bit interested in the treat but kept looking for the squaker (she didn't see it in my hands). After she calmed down and stated playing in the yard, I did it again - she went crazy looking for the squaker and trying to get a hold of it. She totally didn't care about the treats. I put the squaker away and she nearly turned the chest over that I put it on trying to get it. She's been sitting at the door of the room it is in ever since (sometimes scratching at the door). So, what does she want? I thought about getting a stuffie that I keep with the squaker and only let her play with it when she comes. I'm also thinking that since she responds so well that I should just put it away and hope I never need it but know she will probably respond to it if she ever gets out. Thoughts? Thanks!
