Is this for you??? If so then how old? Depending on how old he or she might be going through the "Gangles".
The Gangles is the 'awkward' stages they go through in their development as small pups. i.e. one week they will look fine, the next they seem all legs, the week after they are nicely in proportion, then suddenly put on another growth spurt and look much too long in the back. On and on it goes for months.
The heads do flatten out a bit later as they mature. Amber is 13 months now but still has a tiny 'baby' head in comparison to Bobby who has just had his 2nd birthday.
