From Pawsta's foster mom: Since Pawsta has been with me he has built a lot of confidence. I have introduced him to several dogs and he does well regardless of size and age. He is potty trained and getting better with cars. He still gets very nervous of men wearing baseball caps and small children. Kids 7 and above as long as they respect boundaries he is good, toddlers no. Pawsta is very intelligent, treat motivated and eager to please. I have never seen any aggression from him, only nervousness.
