Ok first let me say that I have house broken many puppies over the years and know how to crate train a dog with success. I have a 4 month old male beagle pup that we walk at least every hour and even though he urinates outside sometimes he will go on the floor in the house 2 or three more times after being walked. I have no clue how he can hold that much liquid in his body to begin with. In the morning when we first take him out he urinates for a long time and empties his bladder but the rest of the day when walked he seems to be more marking his territory when walked instead of really emptying his bladder out. He has had all four of his initial puppy vet visits and I doubt he has any kind of infection. Im thinking its a training issue. Any advice?
