Old Dogs, new tricks

My old (almost) 15 year old Samoyed dog has learned a new trick....peeing in the kitchen!  I realize that as dogs get older, it gets harder for them to maintain bladder control.  To be honest, I'm thrilled that he's doing it on the tile floor rather than my rugs or hardwood floors throughout the rest of the house.  Heck, I'm still amazed that he can climb the front steps to get in and out of the house.  Anyway, I cannot discipline him, since he can't help what he's doing.  What I did manage to do was buy puppy pads at Big Lots (cannot sing the praises of this store enough) for only $4.99.  It has worked wonders with the pee smell...it totally gets absorbed in the pads...and my beautiful baby is smart enough to know to pee right on them!..such a good boy!  His birthday is in July, and he turns 15 this year which is quite a milestone for the breed.  I just hope that this is the last trick he learns!
