River is an old soul looking for his soulmate - could you be his person?  River had a tough start in life and came to PAW quite frightened of the world.  With the endless love and dedication of his foster family he has begun to feel secure - and to blossom.  Now he needs to find his forever home where a loving adopter will continue the process to help him to become the dog he is meant to be. River is a gentle giant.  At 2 & 1/2 and 70 pounds, he is a big fluffy love bug.  At first River can be anxious around new people and in new environments - but once warmed up, he loves people (including children) and other dogs. In fact, River must have another dog in the house as he follows the lead of his current foster brother and has learned so much from him! River loves running and playing in the yard.  Because he is still working on leash walking, River's forever home must have a fenced-in yard.  It will be important to continue leash training and exposure to new situations. This is the best way to build River's confidence and to teach him that the wide world is a fun place to explore!  River's daily medication helps calm him down, and this is something that his forever person will need to continue for River's benefit and comfort.  If you think you could be the one for River, apply to adopt today! PAW places animals in the DC, MD, northern VA, and southern PA area only. ##1836418##
