Pet sitting with Ruby, Bubba and Spenser

I think they like this cooler weather.  Everyone wanted to play this morning.  While Spenser was eating, I went in the yard with Ruby and Bubba.  They both played:  Ruby was even prancing around (just a little bit.)  I did notice she stumbled yesterday coming up the stairs so I was easy with her this morning... I don't want her to overdo it.  I tried throwing the frisbee for Bubba but he wasn't going for it.  He was funny.  He looked at me like I was crazy.  Spenser like it though! I do think that Ruby and Bubba might both have eye infections.  They have green gunk oozing out of them :(
