"There must be a probe. There must be legal action into the matter," Baliyan told reporters.
Describing the incident as "unfortunate", Baliyan said that if treating of pet dogs in West Bengal had become a problem then the Centre would open up a veterinary hospital to solve it.
"If it is such a big problem then we will open a dog hospital here," the BJP MP said adding "strict action must be taken" in the case.
Meanwhile, a delegation of BJP workers, led by actor-turned politician Locket Chatterjee, today demanded that the name of the owner of the pet dog be revealed by the hospital authorities within 10 days.
