by 8 weeks my pups are on as much food a day )maybe a bit more) than the adults spread over 4 meals.
They should stay on 4 meals until about 12 weeks, and will be eating increasing amounts.
With mine by about 4 months they are eating half as much again as the adults, which I gradually start reducing from 9 months so that by a year they are on just a bit more than the adults, and then adjust accordingly, some continue on slightly more, some come into line with the other adults sooner.
They stay on 3 meals until around 6 months then on two to 12 months. My adults are on one meal a day, though many owners prefer a small breakfast and then a bigger evening meal...
