Only thing that has been different this week is that I got him some "new" bully sticks the other day. He has had these for the last year and never had any problems, but these were from a different store (Costco). He has always gone once a day like clockwork. No straining or diarrhea. Am thinking this could be cause of constipation??
Also, my mom has come for a visit, could a change in people in the house be causing some psychological event? Just trying to figure this out.
