They can usually get up to 7' 2" when fully grown on their back legs. I have one and one of their many qualities is that they are extremely friendly.

No way, Irish wolf hounds can attain a body length of 6'2 from the tip of the nose to the tail, and 6'5 at tops. On average they're the largest breed of the domestic dogs and second largest breed of the whole Canine family, the largest would be a Tundra Wolf at 6'11-7'9.
