My puppy turns 4 months old January 30th and had been on Adult (ALS) food for about 5 weeks now. I did a slow transition from 9 weeks (when he came home) to 12 weeks. The breeder wanted all the puppies on adult food by 4 months ol. Many breeders start the puppies on raw or adult when weaned.
Also, he is being fed twice a day now instead of 3 times a day.
I bought Gbbar a big bag of pro plan puppy food when I got him. He is 4 months old tommorow. I plan to switch to adult food the moment the bag finishes (another few weeks) and am going to start cutting down his meals to twice a day tommorow.
Our kids stopped the mid day meal on their own in the 4th month. We went from puppy to All Stage food about the same time and use veggies, treats in the afternoon for training and gives their tummies something to tie them over until supper.
Theres really only two main differences between puppy and adult food. 1) the size of the kibble and 2) the ingredients.
I use adult Blue Buffalo (salmon variety) its a med sized kibble and my Sully LOVES IT!
and its completely grain free which, if you do your research, is best for Goldens and their longevity.
I started Sully on it at 4 months (when i got him from the rescue) and he was only 19lbs (severely underweight). now he's almost 6 months and a healthy 40 lbs!
a good quality food means EVERYTHING, in my opinion.
I'm wondering this too, mainly because Buddy actually steals my older dog's food! He seems to prefer it; I'm not sure if he prefers the fact that it isn't his or if he just doesn't like puppy kibble.
Right now we're feeding Science Diet (I know, I know) Adult Small Bites for Hiro, the adult dog*, and the Science Diet Puppy for Buddy. Buddy's three months old.
*isn't it weird how some adult dogs - even big dogs - refuse to eat large kibble? When I was a kid, I had a chow-husky mix and she would not eat the bigger kibble, but her companion dog, who was a much smaller chow mix, would eat anything.
My understanding (based on my own research) was that you should keep a puppy on large breed puppy food until around a year old because they should be finishing up puberty/most of their skeletal growth by then. The idea is that large breed puppy food helps to slow down skeletal growth, allowing growth plates to fully fuse into dense bones rather than grow too rapidly into long /weak ones. The large breed puppy food usually has adjusted protein, calcium, and phosphorus levels to regulate skeletal growth. Regular puppy food, all life stages food, and adult food just won't do that.
