My wife and I currently have two dogs - Penny, a 14-year old Jack Russell, and Arya (we often call her Arry). We're looking to rehome Arry at the recommendation of our veterinarian due to her increasing aggression toward our other dog over the last year or so. For transparency, I want to share the series of events that have led us to seek a new home for our sweet girl. Last August, Arry attacked Penny, who required stitches in both her face and shoulder. A month later, she attacked Penny again and the damage she caused was even worse. We were told by the veterinarian that Penny was lucky to have survived the attack because Arry tore her neck open and just missed the artery. The veterinarian said that the aggression is a dominance issue that will only get worse over time as Arry perceives Penny to slow down with age. The veterinarian recommended either rehoming one of them or putting both dogs on medication and keeping them separated at all times. We chose to try the medication, but it caused seizures in Penny. We also tried to give them each their own spaces in the house, but neither dog was happy when no one was in their part of the house and they would understandably cry, bark, or scratch. We have given them all this time to try to adjust to the new living arrangement, but it is just not working and is really not fair to either one of them. Whenever one of them is alone in their designated part of the house, they are miserable. My wife and I have finally come to the conclusion that Penny and Arry would both be happier if Arry was able to go to a home where she was the only animal (she has killed two ducks and a hamster in addition to attacking Penny). It breaks our hearts, but we truly believe it is what is best for both her and Penny. Arry is great with people and loves kids - she's fantastic with our six-year old daughter and eight-year old son. For an older girl, she is still very playful and thinks she's still a puppy. She loves to snuggle and share a snack on the sofa. She's a very loving and sweet dog. She's house-trained and rings a bell hung on the door when she needs to go out. Arry needs to have her food measured out or she will eat too much and gain weight very quickly - she's been on her fair share of diets in her nine years. Arry has your stereotypical 'small dog syndrome' and enjoys notifying our family when the mail carrier or UPS driver arrive, when the neighbors walk by the house, or when the wind blows a leaf across the yard. But for all that energy, she's quite content to curl up like a cat on the back of a sofa or bask in warm rays of sunshine on the floor for hours on end. Arry needs a home where she will be able to be with her people whenever they are home, but she is crate-trained for when everyone is at work or school. She really is a wonderful girl on her own, but just can't handle other animals.
