We've always put up trees with all our dogs and have not had them do anything they shouldn't do. They haven't even barked at the tree or peed on it. Some people have had their dogs gobble down a broken glass ornament, though, so you need to be rather circumspect about what to put on the tree and where.
You could try putting the tree up and leaving it undecorated for a few days to accustom him to its presence and see if he's going to try anything. Then hang ornaments higher up to discourage him from sampling them. It makes for a rather unbalanced looking tree but if you want a tree, you might need to make some concessions. If you put ornaments lower down, I'd hang some that won't break if they get pulled off or hit by his happy, happy tail. And don't hang gingerbread ornaments or pork chops or anything that smells too tempting!
Another thing I usually do is tie the tree to something maybe shoulder height to lessen the risk of the dog pulling it over. In our current house, the tree sits in front of a window that opens, so I can tie some twine around the trunk of the tree, pass it through the blinds, and loop it over the window lock. I don't tie it very tight, just enough to keep the tree from slamming straight down into the middle of the room and the ornaments flying off and breaking everywhere if some dog gives anything a tug.
I don't put any decorations on table tops or the coffee table where the dogs might try to grab them or knock them off with their tails. No lovely candle scenes for us. If a tree is up, the dogs aren't allowed into that room if I'm not home to supervise the activity. After a day or so, they usually decide it's not too interesting anyway. Good luck! Be good Packer!
