Lucy is a rescue who came to me un-housebroken, un-spayed, underweight and with a variety of skin infections. She is prone to hotspots from allergies, which are now easily managed by a high quality kibble and raw food diet. She has had atleast one false pregnancy in her life, which made the spay a challenge. Lucy also developed at stump pyometra after her spay, which required an emergency secondary surgery. Additionally, this poor girl seems to have a malformed joints in one of her hind legs, which she tends to favor. Despite how much she seems to try to hide pain, the bum leg does slow her down a little in cold weather. The pyometra was rather difficult to diagnose because of her tendency to hide discomfort. Never underestimate these dogs desire to not make their humans worry. Lucy is very perceptive to what her humans want from her, and was completely housebroken in a matter hours. She does tend to nibble on the corners of blankets when she is nervous about me leaving the house, but is generally not destructive. She definately knows what the rules of the house are, and likes to make sure that EVERYONE is following the rules, haha. I started her in obedience school the day after I picked her up. Though she can be stubborn if she feels a command is pointless, she always listens when the chips are down, and very much wants to make her people happy. Lucy has never shown an ounce of aggression toward adults, children, dogs, cats, etc. She does however desperately want to make friends with EVERYONE, and doesn't always register that other people, and dogs, may not be as keen on being friends. Much of her socialization training has been me teaching her to let me decide when/whether someone wants their personal space. She is a wonderful, patient, caring dog. She has helped rehabilitate my other rescue who had terrible PTSD. Literally the only thing that can rattle this girl, is the fear of losing one of her pack. She mourned the loss of her little rat terrier friend for months, and lets out a paniced whimper if my other dog suddenly becomes quiet in the back yard. She is a dog that requires a canine friend and lots of snuggle time with her humans to be her happiest healthiest self.
