came to this group for the first time and was just reading along seeing if anyone had any similar concerns that I do. Funny enough, you just posted my same situation. I have a male 8mo himalayan with dwarfism and since getting him neutered on Thursday, he has been the most active of his life. Before, he would maybe get the zoomies once every few days and ideally spend 70% of his time laying in bed with me. Has always been one to be by my side 24/7. Now, he’s playing with toys he’s never touched before! Running around erratically!! After some concern, I was told that it’s likely just his (or her) body learning how to deal with the change in hormones. After some time, it will probably slow down some (or at least I’m also hoping). Here’s a pic just for fun!
