So the two dogs grew closer and closer day by day. Everyone at the shelter was aware of the fact that Merrill and her eight-year-old Chihuahua friend Taco were the best of friends. They were actually brought to the Rocket Dog Rescue together during the same time. Where these dogs had resided in the past could not be found out by the volunteers. So where they came from remained a big mystery. It was, however, very heartwarming to see these two form a close bond as best friends. You could say that they were an inseparable pair. Just a few moments of being apart made either one cry. That was how much Merrill and Taco were fond of one another. The people at the shelter knew that they were both very dear to each other but what Merrill did surely surpass all their expectations of them as friends.
