add each breed's average weight together and divide by the number of mixes it has. that average number will be what your dog should weigh when full grown, give or take 10-15 pounds.
75-95 lbs., for a German sheperd
A full grown pitbull can weigh 50-150 lbs
It depends on how rough the boxer plays. The boxer could accidently hurt the ferret because he/she is a lot bigger than the ferret.
About a year and a half.
You can star him early with a training called clicker training.
Puppies have 28 milk teeth and the grown up have 42.
They reach the full maturity at 3 years.
the pitbull terrier is NOT the strongest dog ever but the strongest dog ever is the great dane(only full grown though).
jimmmy Guerrero is cool
I have owned three different German sheperd females from puppy age on. They typically stop getting bigger at approx. one-and-a-half years or so. They are somewhat late at maturing emotionally as well, having gotten over most of their puppy-like quirks by about a year old. Hope that helps.
The breeder will be able to tell you wath you can spect in size from the they dogs they have been breeding.
Impossible to tell being a mix.
