I know these posts are like a year old, and I also know it has to do with large breeds like Great Danes, but I need some advice. I have a 2 month old doberman puppy mix and she has been knuckling over. It started when she was smaller, we noticed her front leg would shake while she was sitting, we thought she was just getting used to her weight so we ignored it. 2 weeks later which is around now, she looked a lot worse while she was running outside. She started to run with three legs. This is when I realized something was actually wrong. I looked it up and realized she goes back and forth from normal to stage 1 and 2. The more active she is, the more it looks like stage 2, the less active it looks like stage 1, and when she is asleep most of the time then starts walking it looks normal. This led me to believe it is just knuckling over and nothing worse that would need immediate surgery. I have concluded many reasons to why this happened to her. For one, all we have is tile/hardwood floor throughout the house, for two, we switched foods many times, and lastly, the food she was on had like 27% protein. After reading many posts I’ve concluded she needed lower protein so I went and got her 21% protein with no by-products or corn. It seems to have been helping because her paws look normal right now, but she hasn’t been as active since we don’t let her play anymore with her litter mates. We had a litter of 8 puppies, which the other 7 are all normal and they’re still on the 27% protein. All seemed great until I read that when they have knuckling joints their supposed to be on low fat too. I read the label and the food she’s on is 21% protein and 16% fat. I’ve concluded this is too much fat so now I am wondering if we should once again switch foods on her. What do you guys recommend I should do? Buy a high quality adult food that is 21/12? Or keep her on what she’s on? I feel if we did that she would get too heavy for her paw. But I feel if we switched foods again which will be like the 3rd or 4th time it will make problems worse. What should I do? if I had to make a diagnosis id say she’s looking pretty normal at this point. But I think that’s just due to more sleep and walking and less running and playing. Also I read that vitamin C is good, but she won’t eat her food with the crushed up pill in it. If anyone still comes on here please help us out because we don’t want her to get worse
