This is my 8yo ds and our 5mo Great Pyr pup. They love each other so much! And yes the pup, Tucker, really is 5 months old in this pic! I'm expecting him to top out at about 140lbs when full grown. This is our 2nd pyr. We lost our 1st one to heart disease this past year. It broke everyone's heart. Dh decided right away that we had to get another. Tucker has definitely carved his spot in our hearts. These dogs get really big but are gentle giants....unless you mess with their kids! Tucker won't be full grown till about 2 years of age but he is already "guarding" the kids. He lets anyone walking down the road know that he is on duty and they better leave his family alone. My dh works out of twon all week and having a dog that watches us is helpful. I know that at night no one is going to be sneaking around the house. And oh the bark Tucker is getting. He's loosing his puppy squeak and getting his big dog bark. That booming bark will wake the dead in the middle of the night lol!
