Understanding how quickly your springer spaniel will grow may help you cope with his frisky growing phase. Every dog is different, but if your springer spaniel is like most of his breed, he'll reach adulthood by 18 months.
How big is a full grown springer spaniel?
English Springer Spaniels weigh between 45 and 55 pounds and stand 18 to 22 inches tall at the shoulder. Field-bred Springers are generally a bit lighter than those bred for the show ring.
Do Springer Spaniels ever calm down?
Helping your Springer spaniel to calm down is not as difficult as you may think or as some 'experts' might suggest. First and foremost remember that he is a dog and that you need to help him. If he is hyperactive then you need to help him to deal with this to help him to become a calmer dog.
