My little dog is getting old and its beginning to affect him. Hes 11 1/2. Going blind and recently has been having a hard time holding his blatter. We have taken him to the vet and there isint anything they can really do for him unless we decide to put him down. Hes been having accidents in the house. At first it was only on the floor right infront of the door. But recently hes been peeing on things. (The leg of my kitchen table most of the time) well this morning he decided to pee on my son's bean bag chair that he LOVES. So trying to salvage it I decided to take all the little balls in it out and put them in a bin and wash it. Welp a bin two boxes and a trash bag later its empty and in the washer. I put AJ down for a nap and I took my other dog out to pee. AJ decided to sneak out of bed and dump the bin😭😭😭 there are little white balls everywhere. He tracked them through the living room and his bedroom. Ive vacuumed the whole house twice and swept all the hardwood and I'm still finding them everywhere.
