My girl is 9 weeks old right now, nice little lab that's getting the hang of the retrieve. I've been using a plush squeaker bone for her retrieves or a tennis ball and I bought a tiny canvas puppy bumper that weighs almost nothing. She's super excitable with the bone and I was wondering what are the best bumpers for a pup? I was thinking of getting a Dokken Teal since the chukar is a bit hard for her to carry, along with the normal size canvas and plastic bumpers. Is the squeaker toy ok for right now? I haven't been worried about her bringing it back right away I just let her play with it. However how can I get her to give up the bumper? She clamps down on everything she gets in her mouth and growls and tugs. I've been putting my finger in her mouth and gently opening it while praising her and I throw the bumper again right away or give it back to her. I'm new to training so every little thing is making me scratch my head. How can I get her to release the bumpers without having to battle with her everytime or is this just a puppy thing that will fade?
