Toby is 16months and still has three meals. It suits him and there is no real reason why he can't have a midday meal so he'll probably just keep having three

Thank you all very much! The time does vary doesn't it? I changed him from 4 to 3 meals a day at 3 months and I think I may change to 2 a day around 6 months but I'll see how it goes when the time comes. I will always give him 2 a day as I have done in the past, although I know a lot of people recommend 1 a day. My dogs have always been healthy and never over-weight on 2, but they've always had a lot of exercise. Thank you again for all your suggestions.
