Fergie hasent pooped in 3 days everything seems normal she plays ball barks at cats through window and runs to the door to yell at the postman. We only know she hasent because we watch her close. I have read the treatments and thank everyone for them. I will try some of them. My question is I have been giving Fergie Glucosamine for years to keep her joints in good shape. Her vet says it's OK but they are not sure it has any effect (the jury is still out) Anyone know of any downside of Glucosamine could it cause constipation ? Fergies Dad.
