When our rescue Cavalier King Charles died we started looking for something similar. We are both in our eighties so looked for an older small dog that would not need long walks, any breed apart from terriers. When our daughter's friend died from cancer and her family could not take her bichon frise he became ours. That was 3 years ago and he is now 10. During the last few years with his first owner she was not able to care for him properly, no proper routine, lots of time in kennels and not many walks. Just before coming to us he had to have 14 teeth extracted. He settled in with us from Day 1, very lively and quickly became particularly attached to my wife, following her as she moves around the house although she is a bit disappointed that he is not a lappy dog, preferring to lay at her feet. He quickly learned our various routines and is now the centre of her life. He has always been a bit stubborn but over the last few months this has developed to become a serious problem. Before going out for a walk I put him on the utility room worktop to brush and comb him. For some reason he has taken a dislike to this and also to having his harness or lead put on. It has now got to the point where he has bitten both of us when we try to pick him up or even just put his lead on – I've had 2 visits to A&E. 95% of the time he is the perfect pet but the increasingly unpredictable 5% is a constant worry. He has been checked by the vet who can't find any physical problem, and he now exhibits this aggressive behaviour at other times when something upsets him. I suspect that it could be that he now sees himself as the pack leader, but whatever the cause is we have a severe problem. We have had advice from a professional trainer and numerous doggy friends but nothing has worked. The problem is compounded by what the effect on my wife's mental health will be when he is no longer with us She will just about cope when we lose him to age or illness but I dread the thought of what having to part with him for any other reason will have on her. She is already coping with a gradual loss of sight and increasing immobility. The only solution I can see is to have all his remaining teeth extracted. I know that dogs can cope with no teeth. Drastic, but it would enable us to keep him without the constant worry of what else will provoke him or the almost unthinkable consequences to my wife of having to ask a rescue centre to try to rehome him. I would appreciate any thoughts on this.
