Dogs Have Greater Potential
Since dogs can be easily trained it makes them have more potential to perform a lot more activities than cats. There are police dogs, dogs that save people, dogs that participate in search and rescue. Dogs that render services (service dogs), dogs that guide the blind, dogs that comfort the sick, and dogs that have the potential of sniffing out cancer and detecting seizures in people.
It difficult to see a cat do any of these things. Although cats have a place in animal-assisted therapy [4], but that’s about it, they can do any of the other respectable things that dogs do.
