We brought Riley home at 9 weeks, the only thing we changed was his feed was at 9.30pm at the breeder and we changed to 8.30pm
He was fed at 7am 12, 4.30pm and 8.30pm
At about 15 weeks we changed to 3 larger feeds, the last being at 7pm.
Its too long for a 9 week old pup to be expected to go from 5pm till 7am the next day.
