I was talking to this woman who knows breeders (non-Shelties) and does agility and we got to talking about Koji. We neutered him at 4 months. She said a lot of agility people neuter early because it tends to make the dogs taller. I guess they become more leggy. I'm not sure if spaying does the same thing as we were discussing specifically neutering. Having said that, I wonder if Koji would've still been so oversized. He seriously must be pushing 18". And yes, he's all legs. (Although, how does he get so much more wet underneath on the wet grass than smaller and lower Miko?) He also doesn't lift his leg. He squats, like puppy squats. I fixed Miko when he was about 6 months, so he's proportionate to what I see in most Shelties. Koji reminds me of a coyote (or a BC). He's got that lopping way about him when he walks. Granted though, makes him fun to watch in agility. Anyhow. Have any of you seen or heard about this? Is there any truth to it? Have you seen it in your own dogs, etc?
