We were quoted £250 for the initial consultation. The behaviourist said she could go to a week-long Boot Camp to learn to be around other animals. I was afraid to ask how much it would be.
Which behaviourist was this? Because these "boot camps" are almost synonymous with people using outdated, punishment-based techniques; old school ex-army and police dog handlers feature heavily. These issues cannot be solved in a week, and the techniques used will make your dog
worse.
Punishing a dog for being scared really doesn't work. At best, the dog will become too scared [of the handler] to bark - so now the dog is double scared. This sort of thing has a nasty habit of causing other, worse, behaviour problems to emerge not long afterwards. Modern dog behaviourists work to change the emotional response of your dog to the thing they perceive as scary. This invariably involves taking the dog from believing that spotting the trigger is scary, to spotting the trigger means a yummy treat is coming.
Furthermore, dogs are crap at generalising learning from place to place. Even if the dog did miraculously learn to cope with other dogs at boot camp, she'd likely not apply that learning to your local park. One week of the dog at boot camp would also mean that you haven't learned anything about how to help your dog, so even if the dog behaves well for the behaviourist, they won't behave well for you because you haven't learned the techniques.
If you post a link to the behaviourist you identified I'll be happy to have a look at their website and see what I can glean (any red flags, for instance, though frankly talk of a boot camp is a red flag in itself).
As I said upthread
*Literally anyone can call themselves a behaviourist, and there's very little correlation between the amount you pay and the quality - I've heard stories of absolute charlatans charging upwards of £800 while the qualified one down the road charges
