My Basenji has caught multiple rabbits and squirrels while on a leash as well. I went to using a shorter leash. At the cottage I have her trained to stay on the property but I do put a bell on her collar. The bell is partly to let me know when she is chasing something so I can ensure she doesn't leave but it's also to let the squirrels know where she is. They tease her relentlessly so if she gets one; it's dead!
The first thought that popped into my head is to make her happy that your leaving. Find something that is a high value treat for her that she really likes but only give it to her once you get home and once she is quiet. Praise her for being quiet and for being a good girl for being alone. Start with 10 min and then make it longer etc. If she associates you coming home as something good, she may feel better about watching you leave. I would also have on music she likes so she isn't feeling completely alone. My last piece of advice is a sweater. My dog hates putting one on, but as soon as she is wearing it she's fine and I find the warmth really calms her. I would put it on in the morning and see if she is a bit more calm and relaxed during the day. Good luck!
If the two dogs were being taunted or teased by a child it is easy to see how this could have escalated to a fight very quickly. It will of course be important to see how the two dogs react to each other going forward but just as important as their reactions to each other, is your reaction to the two of them being together. Naturally both you and your husband are upset and likely traumatized by what happened. Both dogs will feed off your tension when you are all together again and this will make things even harder for both you and them. It's easy to forget there were two in the fight when one is badly injured. If you or your husband are going to be stressed everytime the two dogs are together, then you have a bigger problem so I hope you can find a way to forgive Shenzi and realize that situations like these aren't always clear or one sided. I wish all 4 of you the best of luck with this and I hope you can all heal from this incident and move forward together.
I am also the one who feeds my girl, drives with her to work, takes her for walks etc so she is around me all day everyday. When she sees my mom, she wags her tail, if my mother takes too long to answer the door, she swats at it and cries. When she sees my son, she wags her tail and chortles and screams at him like she hasn't seen him in years. When she sees the controller at my office, she swats at him and makes a plethora of weird noises until he gives her a treat. I think it's kind of like being a mom; your taken for granted because you are alway there but when they want someone to cuddle with, it's you they go to. I wouldn't take it as a sign that he prefers your husband. Your basenji is just not used to seeing him all the time.
I have never had a puppy basenji as mine was a year and a half by the time we got her. The one thing I can tell you from my experience is that if I tried to pass her to someone who is not in her "pack" she would have done exactly the same thing. An acquaintance or a neighbour would not make the cut. In my case, only family and my office staff (which she sees everyday) would be trusted and allowed to treat her in a familiar way. Any one else would have to wait for her to choose to allow them into her circle. That includes a vet who she would hate for trying to put a cone on her head. She is a gentle sweet girl but she has very clear boundaries about who she lets near her and who she will allow to restrict her.
My vet did something that I thought was going to be a disaster but turned out to be brilliant. He had his assistant call in the office dog which was a Boston terrier named Newton. I thought Ember was going to tear Newton to shreds because her anxiety was over the top, instead, they sniffed each other and Ember calmed to a reasonable level where I could control her. I think all dogs fear the vet and they can smell the fear of all the animals that were there ahead of them. On top of that, she can sense my stress when she goes all crazy eyed basenji on me. Seeing Newton, who was calm and unafraid seemed to change her perspective. I understand not all vets will have their own dog for these situations; however, it did make me realize how high my anxiety level was as well. I now make a point of remaining relaxed and keeping her leash as slack as I can so that I don't add to her anxiety.
I have a tri colour basenji who had two of her front nails turn partially black a couple of years ago. I googled it and found that it is common with tri colour dogs to have their nail colour change to black. She has had no issues with it aside from the colour change.
I am from Ontario as well. Bouncing between Burlington and Waterdown. There is a fabulous breeder in Petawawa that will have a litter in late 2019. I have a 6 year old from her now and she is hands down the best basenji ever!! (OK...I am somewhat biased...and I haven't met any other basenji's). The breeders name is Sanda Allen and her company is Africanadian Basenji's. You can find her on Facebook for sure. She did have a website but I don't think it's been updated in years.
