Lab as an outside dog

Question
We are planning to get a dog that will primarily be an outside dog. We have lots of shade and will have plenty of water available. There are some lab puppies available - is there any reason to avoid a lab if we plan on it being an outside dog - are they able to take the Texas heat? During extreme heat or extreme weather we would obviously bring it inside, but do not want a dog that is always inside due to allergies.  Thanks for any advice.

Answer
I am against keeping dogs outside.  No breed will be happy outside all day by itself. There are ways of still having a house although you have a Lab in it.  While Labs maybe less likely to be a barking problem if left outside alone all day, some are.  It is best to leave the dog inside and find a way for it to get a mid day break.
