My dad loved his granddogs also. If I didn't bring my dogs when I visited, he would ask why...
It was nice when I did bring them, as he took care of all of the dogs when I was here... I brought my two Dalmatians, he had his own Dalmatian and a chocolate Lab.... He loved the dogs and would "dog sit" for me when I needed it... He would collect all the dinner scraps and divide them between all the dogs... They really loved him...
