no its not a set rule, it can go either way... typicaly its around 8 weeks of age is the youngest you would want to buy or sell a puppy.
For the first few weeks, puppies are nursed on milk produced by the mother dog. As the pups develop they need to start transitioning to solid food. If assistance from the breeder is not available to produce gruel for the puppies to eat, the mother dog will eat and partially digest food which she then vomits for the puppies to eat. This sustains the puppies while they practice eating solid food until they are able to digest it themselves.
When the puppies are 7-10 weeks or less.
Standard dog food would be difficult for puppies to eat and digest but it is not 'bad' for them in the sense that it is poison.
Yes. I would recommend eating it by the sell by or eat by date
Probably about 80%.
Dogs eating food IS an instinct. Evidence of that is that almost as soon as they're born, puppies head straight for their mothers milk even though they're blind and no one taught them.
When they have been weaned, meaning, no longer suckling for the mother's breasts for food. 8 weeks - no less.
Dog food!
Get some dry dog food at the store that were made specially for puppies.
They probably like human food better than dog food
hi umm you can sell your dog well donate your dog at the dog hotel in the bottom lefty corner it says donate a dog and yep :)
As long as your female boxer dog and male boxer dog are not related, you can allow them to mate and have puppies. It is up to you if you want to sell the puppies or just raise them yourself. If you do not neuter the puppies they will try to mate, but since they will be brother and sister it isn't recommended that you allow them to mate.
