Answer the question about text:

My heart was pounding , I was completely out of breath , my head was buzzing . It took nearly half of the walk around the circle for me to calm down . Granted , this is the first time we encountered an off - leash dog on our walk . But I ' m sure it will probably happen again , and what if the other dog bounds right the hell onto Blake and he spazzes ?

What may be the reason they have never run into a stray dog before ?
They recently got a new dog .
