We adopted our Great Dane from a city animal shelter on July 7, 2007. The shelter estimated him to be about 4 months old, which would make him about 11 months old right now. We know that he's at least over 7 months old because we've had him for 7 months. He was under weight when we adopted him (40 lbs) but he quickly gained weight, but then kinda stabilized at the same weight for quite a while. He's now at 80 lbs. Sometimes only his last couple of ribs can barely be seen and at other times you can barely see his other ribs w/the reflection of the light on his black coat. He is very small compared to other Danes that we've seen of his same age. He is shorter than others and much less stocky. The others we've seen have a lot more loose skin than he does too, which makes me think they have alot more room to grow than he does. He eats about 6-7 cups of food per day. Should we up his food intake? I don't think he would eat more even if we tried to give him more. He sometimes leaves food in his bowl as it is and then comes back for it later. We originally fed him Nutro Natural Choice Large Breed Adult. We have now switched him to Canidae. He acts just like a Dane as far as behavior. He looks just like a Dane, but he's small. Since we got him from a shelter I do not know his history. The only thing that I do know is that he and his brother were both Danes brought to the shelter because the owner didn't realize that they would get big. He was in poor health when we got him. We went through months of various health treatments. Our vet and a local Dane rescue have both said that he appears to be a good healthy weight for his size. Could he be a runt? If so, do runts get to be full sized eventually or do they stay smaller? Could he be mixed with another dog of similar body shape? I looked into the DNA testing for dogs but I didn't find any that included the Dane breed in what they are testing for. Full Dane or not he's a great dog and is part of our family, but I would like to know why he's small. We had him neutered as soon as he was old enough to do so. I've read that doing so can influence size, but I wouldn't think it would be that much. Any ideas? I can't post pics on here for some reason, but you can see his pics in my profile on here.
