We have a very intelligent 5 month old female who had severe problems with diarrhea and a urinary tract infection from 2 to 3 1/2 mos of age. Consequently, she had numerous "accidents" in the house as well as many "false calls" outside when we thought she was signaling (which she probably was) but nothing "came out." Now, it's a confusing problem...she signals at doors to go out and pees or poops appropriately, but other times in the house there is no signal at all. She's had obedience training and was the star of her puppy class so we know she is smart, but for housebreaking - it's all mixed up. She is crate trained and has had only one accident since we got her at 2 mos with a "blow-out" during the night due to diarrhea but no accidents since in her crate. We have to watch her like a hawk when she's loose in the house or she's likely to pee anywhere, any time. Any ideas?
