The Church During Slavery. For our purposes, the account begins in the decades after the American Revolution, as Northern states gradually began to abolish slavery. As a result, sharper differences emerged between the experiences of enslaved peoples in the South and those Northerners who were now relatively free.
In large breed dogs, this very commonly leads to pano, a painful condition that shows up usually between 5 and 12 months of age. Large breed dogs who are fed puppy chow show a much higher rate of pano than dogs who are fed adult food from the beginning. I would make the switch to adult food immediately.
As such, the decision to switch your Labrador to an adult food is not one to be taken lightly. Speak with your vet concerning your Labrador's growth and keep your big, goofy, teenage Lab on a large-breed puppy food until the vet says his growth plates are beginning to close.
