Hello, my family and I adopted a four month old lab pup on Saturday. He's slowly been getting better and better at going potty outside, but I fear that we've gotten into a bad habit of not setting water out for him all the time. We usually give him a couple ounces at a time and spread his water intake over the day because he drinks quite a lot at a time. We just saw the vet and it doesn't seem like there's anything wrong with him, but he's gotten into the habit of sitting in front of the water pitcher until we give him some. Also, whenever it rains and we have to take him outside to potty he just drinks the water despite getting water inside! I know that we have to give him unlimited, but I'm not sure how to as I'm afraid he'll just drink all of it at once and I don't want him to go back on all of his housetraining progress. Any advice?
