biting and living outside

Question
Hello, my GR is 14 weeks old now and the potty training is going smoothly, the only problem is that he is starting to bite evrything. No matter what we do he just continue to bite people. i push him away every time he bites and offer him his toy but he just wouldn't stop biting me and my other family members. What should we do? He bites very hard too! Also there is a day of the week that everyone in my house is busy and no one has the time to come back home to walk him so we thought of building a dog house outside in our backyard and just let him stay there until someone comes home. Winter is approaching and I'm scare that he might be cold but there is no other way. No one has the time to come home. Its just one day of the week that all our schedules are packed. Please help us.

Answer
Young Labs, which I know best, and other puppies tend to very bad about biting. You see a litter of them, and all the ones that are awake are biting another one or themselves. I am not even sure they realize that when they are alone, if they quit biting, they would quit being bitten. At 3 to 4 months they are getting their adult teeth, and it seems they spend every waking moment biting or chewing. One thing you can do at that stage is to knot and wet a piece of cloth. Then freeze it. The cooling will soothe the gums. Only let the puppy have it when you are there to watch it. I maintain a Lab's favorite chew toy is another Lab. Otherwise they settle for any person they can. They keep hoping to find one that won't yelp, jerk their hand away, and leave.

You just have to keep on correcting them, hundreds of times, not dozens. Provide sturdy, safe toys such as Kongs and Nylabones. Avoid things they can chew pieces off and choke on them. Keep them away from electrical cords. Crates are essential for most young Labs and other dogs.

The pet stores are full of toys that many dogs will quickly chew up into pieces they could choke on or cause intestinal blockages. If you are not there to watch, stick to sturdy stuff such as Nylabones and Kongs. Keep a close eye on chew toys and quickly discard anything that is coming apart in pieces. Rawhide is especially bad because it swells after being swallowed. I don't trust any of the consumable chews. The dogs just gnaw them down to a dangerous size too quickly. These problems are the worst with, but not limited to, large, aggressive chewers such as Labs.

Have you tried to find a neighbor or professional dog walker to give him a break days you can't?  When he is a little older, he could go to doggie day care if available

I don't like to see a dog left outside by itself.  They can become a problem barker.  They can be stolen or get loose.  They can be abused.  If it is only one day a week, he won't develop the coat he needs to stay warm.
