Its upto you to think the way you want! Both are good in their own ways!
Cats by nature think they are kind of tigers(their bigger versions!)! And dogs believe they are dogs(no offence meant and they are proud of their kind) and always consider humans to be their masters!
Cats take their master out for a walk by leading from the front! And dogs always love when their masters take them out for a walk!
