Thanks everyone, I have not read any actual studies linking high protein to weak or down pasterns. Just our trainer, online articles and some forums. Given that our trainer mentioned it, then I saw it on the forums, I figured there were studies or evidence based articles stating that there was a link and I was just not finding them.
Thanks for the tip on avoiding the higher calcium food, we were warned by the vet to stay away from additional calcium whether in food or supplements. I just wasn't sure what was considered high. Great AAFCO article by the way, thank you for posting.
So it seems like the high protein link to weak pasterns may not be evidence based? That would be great since he is doing really well on Victor food. I wouldn't mind switching him to the 26% protein food even with the added grains, I just wanted to see if there was some downside to too much protein and what was too much. I would think that a working line dog would need protein, but again, I am just going by forums.
Also, yes, he is crated, I am not sure that I would say a lot. If we can't monitor him 100%, he is in the crate. That being said, we usually tether him to us so we can keep him close. The crate is much taller than him and he has plenty of room. He has been very good with the housebreaking so I opened up the crate quite a bit to give him plenty of room. When my wife and I both work on the same days, he is crated for a few hours at a time. I go home to let him out and let him run in the yard. My wife works 3 days per week. Since she has days off during the week and I do the weekends he is out of the crate quite a bit. I always have him out for at least a couple hours before bed. But, he does sleep in the crate and again, when we just can't keep an eye on him or he is getting a bit too rambunctious or bitey, he is in the crate. He doesn't seem to view it as a negative, he usually hops right in when I grab the kong knowing a reward will soon follow.
