I believe if he had a vitamin d deficiency you would see it in all his joints and bones , not just a lack of acetabulum depth ...... give him fish oil , it should at worst be harmless ...... i'd find him a quality kibble and start with the least amount for his age and weight , and never look at the recommended amount again , just look at the dog ...... you talked about wolf pups , wild dogs are almost never dysplastic , and usually the ones that survive to adulthood have had to survive starvation at some point in their growth ....... I had a dog that weighed 150-160lbs as an adult , she had a problem as a pup and became anorexic , the vet and myself thought she may starve to death , she lived to almost 9 , died from cancer , she was orthopedically perfect , i'd guess she would have ofa'ed good or excellent .......
Thats why I started the topic as mentioned in the first post all the bones are showing thin walls, if it was just the sockets I would be a little less concerned, as you and others say the hip diagnosis isnt necesarily the be all and end all, but all his leg joints were x-rayed and the overall picture is one of thin walled bones caused by insufficient calcium content, which could be low calcium intake, but would also be classic rickets from lack of Vitamin D. Either one is my fault. But having looked into it, I cant see anyway he would have been getting sufficient Vit D on his raw diet . Calcium he was certainly getting some of.
Arden Grange is a brand in the same sort of price bracket as royal canin, have a pretty website http://www.ardengrange.com/index.asp claim to be made of all the best ingredients etc etc just like everyone else. Some users report less tendancy to put on weight and smaller poop on AG vs Royal Canin, I dont doubt other users would report the reverse. We've got a big sack in will see how it works.
I think its a shame the dog REALLY enjoyed real food, actually working on the food instead of inhaling it, and produced really nice firm poop.
