Did the breeder give you any instructrions on feeding? I know with all my dogs I got instructions with information on feeding, worming, exercise, vaccinations etc.
4 meals to start, then at 10 weeks down to 3 meals , then down to 2 meals at 6months (I also got the time of day to feed to begin with)
At the moment Roly is fed at 7am, 12pm and 5pm, when he goes down to 2 meals, he'll be fed at 7am and 4pm.
Roly's going to be in for a shock when we go down to 2 meals - he really loves his food! I'll have to give him a biscuit at lunchtime to keep him going.
