So.. We've been thinking about adopting a new puppy. WE have a 2 year old female blue tick coonhound, which we rescued from our local humane society. We've had her for a year, so when it comes to details about her history before she joined our family; we are kind of in unchartered waters... About 3 months ago, we located a red ticked coonhound on petfinder, and we fell in love again. His foster mommy dropped him off for a "trial" visit. We had him for 3 days, and all went well. Our girl was very accepting and not once did she try to compete for attention. But, on the 4th day, something changed. Not sure what. I was on the porch with Bailey (blue tick) and Jack (red tick) came running up to me for kisses. I'm not sure if Bailey was cautious because he sort of came out of no where, or because she didn't know what he was going for. She proceeded to attack him. Jack weighed about 25 more pounds than Bailey, and he submitted right away. I broke them up immediately, and they had to remain separated for another whole day until his foster mommy could come back. He was a very shy and timid guy, so I didn't want to put him through all that stress at once. But every time Bailey would get a whiff of him, her hair would stand up, and she'd be ready to go at it again. I never understood why. Was it to show dominance? Was she scared? The neighbors across the street have HUGE chocolate labs that sometimes get out of their fence. And for some reason, like to investigate our yard, and when Bailey sees them, she’s the most playful thing. Runs out and they will romp around and play. She has play sessions with the neighbors golden. She gets along great with them. Would it be a good idea to introduce a puppy? We were thinking of either a lab, a golden, or even and Irish setter. I'd feel better starting with a puppy, that way it’s something small and gentle, not someone bigger or the same size. Am I making sense? I want a dog her size, so she can play around and wrestle with, but I'm thinking a pup would be better because she'd get the chance to grow with the puppy and learn to tolerate certain behaviors...
I had a similar experience several years ago. We adopted a gorgeous female cocker spaniel from out local humane society. We took her home for an overnight "trial" to make sure she got along with our other dog and all was great. Returned to the shelter the next day to make things official. Once again everything was fine overnight. The next afternoon, however her entire personality changed. She became very aggressive towards Dudley and attacked. She actually bit and punctured an artery in his leg. We decided to return her to the shelter and ended up waiting a few years before adding a second dog to our household. We ended up adding a male Maltese, who refuses to admit he's a dog. They are both extremely laid back so we've never had a single problem. A few years later we added a Rottweiler puppy to the mix with great results.
I'm in no way an expert, but maybe you should consult a trainer in your area. Also if you add a puppy you should make sure that you can segregate your dogs if problems arise in the future.
Maybe introducing them on neutral ground before coming home would help. The neighbor dogs play in their yard, then come over, then leave. This dog came out of a car and stayed, then tried to kiss her person! Where did he come from? and why won't he go away?
Your dog doesn't understand that you picked him. The introduction is important. Meeting at the dog park (or somewhere) and walking them home together might help.
I took my dog to meet the new dog at the rescue and we all went for a walk. Then I took my dog home and picked up the new dog the next day. I took her for a long walk before going home. Then we walked right in and he greeted her fine. She was too tired to explore much and let him sniff her all over.
Over time he has put her down for being too aggressive to him during play. She is actually pretty aggressive, so it is not as though he is bulling her. It is usually because she has hurt him.
