This a question I ask myself often. My answer to this is that it is because they are very very special animals and we sometimes do not appreciate how special they are. Most dogs regardless of how they are treated by us show us such undivided loyalty and affection. This should be respected and we should thank them every day for putting up with our inconsistency and unpredictability
Recall is one of the most regular behaviours I am asked to help with because if a dog can’t recall back to you in distracting or potentially dangerous environments the result can be at best annoying and embarrassing to you and others or at worse potentially dangerous for your dog and frightening for you if your dog is out of sight or have got themselves into a situation they or you are unable to deal with
Spaniels are full of personality, loyalty and have boundless energy and because of this they have long been chosen as companions for families. If you are new to spaniels being aware of their overriding hunting instinct that dates back centuries is important for your sanity and your relationship with them that you understand these instincts which underpin most of the activities, they enjoy.
