Caring for a dog

We had our first dog when I was already middle aged. Although we had dogs in our house before when I was living with my parents, this time it is my own house. It ididn't occur to me that dogs are like companions who can take away the stress of the daily life. Especially when my wife comes home from work, she would be welcomed by our dogs and that scene would definitely give her spirit a boost.

Being enamoured to dogs, 2 of our dogs are sleeping in our bedroom and one sleeps in the housemaid's bedroom. So if you need a companion who would always understand you, get a dog and you will have a life.

Dogs are a good companions but far away from understanding humans, I wouldn't go so far because dogs are made up to suit humans and to serve us, so any other connotation is just a nice fairy tale that we tell to ourselves.. They need a pack leader to follow and it makes them easy to control.
I think you ment to say 'you will have a better life' and not 'a life'.
