I have to add..
I do like people too, I find people endlessly fascinating, interesting, amusing, lovely, horrible, kind, mean.. etc
I have to be able to get on with people and connect with people IRL or I can't do my job (teach them how to fix the relationship problem between them and their dog)...
I do get VERY ragey at the people who ask me 'how do I get to be a dog trainer/dog behaviourist, because I want to do that as I don't really like people I prefer animals'..
And I have to break their bubble - being a domestic animal trainer/behaviourist means you MUST LIKE PEOPLE... its non-negotiable!
If you don't like people and are not a people person how on earth can you explain the problem and motivate them to put in the work necessary!
I also appreciate I like animals FAR more than most people, I wouldn't expect my clients to dedicate the same amount of time and money to their dog as I do with mine - but dogs are my life, both as a hobby and as a job - for most people dogs are just a part of life and that is fine.
I am not however, a raving lunatic - there ARE far worse things than being PTS for any animal, this awful attitude of 'we must preserve life at all cost' or 'we must save them all' is utter bollocks. Have these people even looked at that first line... 'at all cost', really, even the cost to the ANIMAL itself?
There are a lot of questionable practices in rescue, such as shipping from overseas, dogs that have been street dogs in other countries instead of putting money into education and spay/neuter/vaccinate programs!
