With my big yard and love for long hikes your pet will be happy and active. I have had dogs my whole adult life, and have owned and worked with very big and/or reactive dogs, so know how to handle them. I also volunteer with a rescue, helping in their kennels and with their foster program. I work from home so my schedule is always very flexible and I am never gone for long. I have a large fenced yard with lots to sniff. During the hot months with have a doggie pool to chill out, and we always spend the cool evenings snuggled up inside the house.
