We were very nervous about putting up a Christmas tree this year. We got our border collie in May. He still acts a bit like a puppy since he's only 20 months old. I was actually afraid he might pee on the tree since he pees on every single tree, bush, fire hydrant, post, light pole that he can find when we are out talking our walks. But, thankfully, he has not peed on the tree!
We have had cats for 14 years. Because of that we have our tree as pet proofed as we can. We don't use garland or tinsel. Instead we use long strands of very sturdy pearls. I have several foil bows to give it the sparkle of tinsel or garland. But, I put them higher up on the tree because I am almost positive he would try to eat those. We have decorated all of the tree including the bottom branches. We have watched him closely to make sure he doesn't try to take them off and eat them. We thought for sure he would because he has a habit of running off with the girls toys and chewing on them. He has only taken off one ornament and we caught him right away. He hasn't done it since.
I do have a few Christmas stuffed toys that I like to set on the ground in back of the tree against the wall. For some reason he keeps trying to grab the little snowman one and take off with it. I decided today that I would just put that one up where he can't get it. I was waiting for him to try to get another one since he couldn't get that one. But, he's left the others alone so far.
