There is no blood in it and he is acting normal (also, it sort of smells like poop now that I threw it in the garbage - now my garbage stinks really bad). I took him for a short walk and he went hunting for mice like he normally does. Then he ate his supper & some of the cats supper like he normally does. He ate a snack and now he's chewing on his "chewie" (a cow hoof) like he normally does.

He has these accidents once in awhile (like every 3 months or something).

I'm wondering about the dog food he had today. It's Merrick (which he normally has) but it's catfish. I don't normally buy the catfish can. Maybe he is allergic to catfish.

I will watch him tonight. The vet isn't opened until tomorrow morning. My sister is dog sitting him tomorrow so I will have her watch him closely.

The blue floor kind of freaked me out. Sounds like I have a permanent stain to help me remember this incendent.

Thanks for answering my questions everybody.

I'll keep you posted on his "issue".
