69 Hi Yossi,
I’m sorry to hear that! When you say that she likes plush toys, but tears them up quickly, do you mean that she tears them up while you play tug or just when she’s alone? Dogs will have preferences for different fabrics/textures/firmness. It’s possible that going through her first heat, may have changed her preference or she had an aversive experience while she was in heat. Will she play tug with the plush toys? What did you previously play tug with her with? Have you you tried leather or sheepskin/sheep wool tugs or even felt tugs (softer texture)? Have you tried back tying her on a harness and teasing her with the tug toy or having someone hold her on leash and restrain her while you tease her with a tug? Using a flirt pole so she has to chase it a bit? Seems like you might have to be patient and ease back into it. Feel free to include a video
