What a gorgeous pair of greys you have. We have 3 retired racers. We lost one at 3 mos. past 10 years on April 1 of this year and he was a big, beutiful brindle like your boy. We now have an 8 1/2, 10 1/2 and will be 13 in a mo. The latter is a forever foster who is doing so well with the other two. She is having pain in hips, lower back so takes pain pills and my husband built a ramp for her (and the others) to use with the 4 steps from our deck to the backyard. She's been with us about 2 mos. now. I volunteer for turnout at our rescue shelter. We got a load of 32 dogs from FL yesterday so I'm anxious to meet all of them on Wednesday. Your greys look loved, and why shouldn't they be. They are magnificent creatures who deserve loving homes. Your dogs are blessed to have you and your wife and visa versa.
