“I’m not sure what the chances would be on actually getting a therapy/service dog. Seems quiet slim from what I’m reading.”
Yep, but, there’s a reason for that - it takes years to train them and they don’t all make it through.
Take guide dogs, they’re bred to do it, as in they have their own breeding programme, they’re raised and trained to train to be guide dogs, then they’re actually trained to be guide dogs... and at every point in that process dogs fail and are withdrawn from the programme.
Other forms of support dog don’t even have the breeding programme so it’s even dicier and it’s hugely labour intensive.
So honestly, the chances of being able to just get a lab puppy and managing to train it yourself to do anything like that are pretty slim.
If you want a dog, for you and were going to wait till your youngest was in school - labs are usually a pretty good family pet.
But puppies and autism is hard going, honestly, my DS likes dogs fine, the puppy wasn’t our first dog... he just find it really stressful.
