Pups under the age of 4 months old can start moving around but not much else at this age. They will play and get around a lot but will not yet be able to generate much on their own.
Puppies between the ages of 4 to 10 weeks are similar in this respect. They need to be watched as they play amongst their siblings and will without a doubt engage in some nipping and mouthing.
This is normal puppy behavior. If one of the siblings has the bite of a 'dog' they may begin to develop problems later on and may nip too hard. If this trend continues they may become 'dog' biters. In these cases it is a problem for everyone in the family because we could end up with split ups.
Puppies bite their litter mates at each other and then again as they start to grow up. The biters become confused and will bite each other....that is the way they socialize. You will end up with adorable puppy that has never learned to inhibit it's bite. Boy will it be fun trying to teach the pup a new redirection and behavior. There are a number of ways to avoid this problem. Don't underestimate the power that is unique to each puppy. Use that to your advantage!
1) Simply recondition your puppy to stop nipping.
2) Walk your puppy, for 45 minutes at a time, in the same direction that it's walking. In time, he will learn to change direction when he wants to investigate a new Area.
3) Use toys to engage the puppy. This is especially good for very dominate puppies. They need to be taught that it's OK to 'play' with the items that are meant to be used as dog toys.
4) Every two weeks, take the pup outside to a newly tiled orMoistened grassed area. If he bites or nibbles, firmly and quickly say 'NO!'. Then immediately give him his toy or chew...and watch him jaws the new toy as if he's chewing a treat. (It's almost a reflex.)
5) Every time you see your puppy or dog sniffing around, pick him up and say "NO!". Take him outside and encourage him to go potty. Soon he will learn that it's OK to be inside, but he has to go potty outside.
6) You can also begin to give the puppy bones or toys....you must watch and see which of the items he choose to gnaw. Not all the time, mind you, but sometimes. If you don't mind him gnawing and biting on an old shoe you may give him one. He'll probably then put that shoe in a plastic bag and put that into the garage as his chew toy.
7) When you leave the house, put a heavy wire or plastic crate crate in the back seat area. Put puppy's blanket and some chew toys in with him.
8) You can begin to teach him to rest in his bed oruggets as his bed or toys. He has no way of knowing where you want him to sleep. He can't be left alone for long periods.
9) Socialization with family members and other pups is important during this time. Everyone is a dog lover, and they should begin to play with the pup together. In his Little home. While he is a puppy, he can begin learning simple socializationdon't you think?
10) As your puppy grows, he has to go through teething for both him and his teeth. It's a natural process. So you can begin giving him little toys or treats made of rubber at first. These toys have a ridged or other texture which has a toothbrush on one side of them. You can present this to him and allow him to gnaw on it and then you can give him a better softer rubber bone, or if you have one of these, you can place some of his instruction marks into this as well. The puppy soon gets to know that these items can be chewed, but everything else is fair game.
11) The ideal age to bring your puppy home, if you'd like your puppy to be an outdoor dog, is between eight and twelve weeks. You need to have a secure area for your puppy and a suitable dog house or crate. At this time the best thing to do is take the time to get your puppy used to his new environment. If you have a fenced yard you can allow him to play and get out of the house for awhile. However, until he is fully trained and has settled in, you should keep him on a leash.
