I_ totally empathise with all of you regarding canine dementia. The vet first obviously but please have a look at the Facebook page where you will find loads of helpful advice. I have stayed as a member after Tifi died (naturally, I should add) purely to be able to give help where I can.
I was at my wits' end when totally out of character she seriously attacked her brother who previously she adored. I consulted a behaviourist who was not at all useful. I was considering having her put down but then heard of a book 'Remember Me' by Eileen Anderson that I mention in my earlier post.
It was a turning point for Tifi and me. I joined the CCD Facebook group and found others very helpful.
She improved using various medicines and techniques and went on to have a happy life until finally her kidney function packed up and she died very peacefully one night having looked into my eyes and said her goodbye. She was 15. Unless you've been through this it is so easy to talk of lack of quality of life and selfishness. Give your dogs a chance, please.
Hugs to you all.
My Tifi had CBD in her later years. There is an excellent group on FB who will recommend various medications that help. It's usually necessary to find a balance that'll help. Hopefully, your vet will also prescribe something. If you can join you'll find a great band of friends who understand.
Tifi enjoyed her last years and had a great quality of life although when she first developed it, like you, I thought that she might have to be 'put to sleep'. Please give him a chance and you will find great benefits.
Eileen Anderson has written 'Remember Me. Loving and Caring for a Dog with Canine Cognitive Dysfunction' which is available on Amazon and is a really worthwhile and helpful book.
Listen to your gut feeling. Stop any behaviour that you're not happy with, eeefarm makes a good suggestion to enforce the stop command by having a lead attached that you can step on when necessary. Your B may just be copying by growling but remember she may not! Yes, Basenjis will growl as they play but the meaning is usually fairly obvious when you watch or listen carefully. It appears that you have quite a complicated series of events - try to deal with one thing at a time but always be on the alert. As others have advised, please don't leave them alone together when you're not there. As you indicate that she has a hard head with the rest of the family this would still apply when you're away. Eventually, with determination you'll obtain equilibrium.
Otis looks extremely cute and loveable. Siz and weight are within Basenji Parameters. The pose that others post are Basenji like are a standard play bow exhibited by dogs of all varieties so not really indicative. You're naturally curious but when it comes down to it I'm sure DNA results will not make an iota of difference in your love for Otis..
Check with a specialist about the tumour. Is it definitely contained in the toe? If it's spread I wouldn't have it cut into as I feel that this can set off increased growth. As to having a toe removed, one of my bitches had a toe on her front foot removed because it was badly damaged. The vet said that she would always limp but she was back in the show ring after the operation and not one judge she went under noticed the missing toe! She moved as perfectly as ever.
I agree that it's usually only necessary to reduce your Basenji's amount of food rather than a special diet when he/she is beginning to put on weight. That is if they are on an already balanced diet. During cold months I usually add a little, against during warm months. My vet used to ask "Show weight or normal weight?" !!. Noticing how slim some people keep their Basenjis and especially puppies, in the show ring I agree with him. I allow my old Basenis extra weight to help combat any wasting due to age. In my opinion, it's merely a matter of being aware that they are putting on unnecessary weight.
