I know this is harder in northern breeds than other dogs. Wolves typically outgrow the following tendency around 4 months of age. So do a lot of dogs. They can be house broken. The shortened muzzles of many breeds is a neotenous trait.
Wolves tend to fade in color throughout their lives.
They lighten with maturity. Wolves are not born white like German Sheperds, Sibes, Mals, etc can be. The fading has been halted genetically. I could go on and on with examples of neoteny, both in physical and behavioral characteristics. I think I will wrap it up for now.
