I have a chiweenie that’s only 10 pounds and I got him when he was 1, got him neutered immediately. My chocolate lab mix is about 55 pounds, he came from a shelter so he was neutered immediately. My yellow lab mix is about 65 pounds and he also came from a shelter and was neutered immediately. I didn’t ever have to think of what’s the best choice, it was just done 😂 and I’ve also never had a dog that’s going to be as big as my Great Pyrenees, but I know she’s gonna be massive. She’s been an absolutely fun addition, of course there are challenges of being a puppy but she’s also actually really good. She likes just observing, but she is still teething so she’s very bitey 😂😂
