More: Both Tooka and Emma are rescue dogs from Texas. When Tooka was 2 1/2 years old he went blind (PRA) but it hasn't slowed him down in the least. He excels in agility work and is very athletic. Emma has since turned into the doting little sister and rarely lets him out of her sight. She leads our hikes now and they both have hiked over 500 miles with us in the last 3 years.
