I''m glad I found this because I took my Irish to the vet last night for his heartworm test and he weighed in at 45 pounds. When I got home I pulled out the breed standard which I haven't looked at in a long time and was shocked to see that he is supposed to be 27 pounds. I then measured him (more or less) and he's about 24 inches at the shoulder instead of the required 15. I guess he's a giant, but I have to say I love his size and I get inquiries from people constantly when we are out walking wanting to know what kind of dog he is. He draws a lot of (positive) attention.
