If you plan to adopt one of these superior hunting dogs, it's absolutely recommended that you gather as much information as you can to make a fully informed decision. Below is a bit of American Water Spaniel dogs 101 that will help guide you.
These Spaniels are extremely intelligent yet fragile in their personality. Like a well-tuned model airplane engine, they can do great things but must be handled delicately. They are gun dogs who, once fully trained, will not flinch at the blast but will wither if you get cross with them. They are born with the brains to hunt, retrieve, and more, but they need time and great patience for it all to work.
Despite their tenacity in the field and stream, these dogs are known to be very wary of strangers. Their aloofness even to people they've previously met should not be punished. When they are ready to be someone's friend, and in whatever capacity they chose to do so (from just saying "hi" to hanging out with the new friend), they should be allowed to do so.
The American Water Spaniel requires not just an extraordinary amount of daily exercise but also agility activity and other things to keep them mentally stimulated. As they can get quickly anxious if neglected in any way, this is not a dog to let lie around or be left alone.
