The dog cleans the coast of the Kazanka river in Kazan every day, and when it sees any movement in the water, it rushes to catch it, KazanFirst reported.
It is noted that the dog also cleans Kazanka from specimen fish, hiding it in the bushes. Kazan residents are already accustomed to such an assistant. It is said that the dog was most probably lost, as there was a trace of the dog-collar on it. However, it remains unknown when the four-legged helper has appeared there.
