I have 9 1/2 month German Shepherd / Rottweiler mix who has the body type and face of a Shepherd and the fur/markings of a Rott. He's healthy, happy, athletic, smart, and I haven't had any problems with him so far.
I do think he's underweight by a decent amount, thats if we're going off those average weight by age charts. He weighs about 53lbs at 9 1/2 months, the Shepherd chart says he should be around 70lbs while the Rott is closer to 85-90. He'd even be 10 lbs underweight for a female shepherd.
Now, there are a few reasons why he might be smaller. First off I got him way too early, he was around 6 weeks, still blind with blue-grey eyes. The woman whose dogs had the puppies didnt want to keep them any longer and was getting rid of them to anyone that would take them. They were definitely to young to be away from their mother so that may have stunted his growth. On top of that, I had him snipped as soon I could, I think around 4-5 months. Maybe the combo of the 2 is keeping him small?
On the other hand he is about 23 inches tall, right below the bottom average of both breeds so he's not "small" just skinny. Also, I see 2 of his litter mates almost every day and he's an inch or 2 taller than both and about the same weight. He is obviously skinnier than the other 2 but neither of them is above 60lbs, its not like hes lagging behind.
Can I get some opinions? What do you guys think?
