So true and we have an old dog who has been so loyal to us for 17 years. She looks like a train wreck but to us she is beautiful. It is sad seeign her lose her stamina. She wants to go around trail but so many breaks now she has to rest a lot. She always hated fences, so likes to get out of 1/2 acre fenced yard. She now has a place on front porch with her own screen doggie door in front of french doors so she can be 2 feet from me and see us and outside too.
