Don’t inflict a dog on someone who doesn’t want to live with someone.
Don’t inflict a life in a house with someone who doesn’t want a dog on a dog.
Dogs smell. If you love them you probably don’t notice - he will.
You can’t go for days out anymore - he will resent this
Holidays become a major issue - he will resent this
The cost of vets etc will be a source of contention.
Car choices become dictated by the dog.
Spontaneous days out or trips away become a thing of the past.
They lock everything and make everything stink.
They wreck your furniture
They piss and shit everywhere
They need walking in all weathers
Your son will leave home soon and won’t care anyway
Do you live on a large property with a large plot where the dog could have a large fenced area of the garden to itself and somewhere to build a huge dog house/kennel with secure outdoor space and an indoor area that’s heated/cooled depending on time of year and space to then have another dog to keep it company? If not personally I think it’s cruel on the animal any.
Ps - they stink, and make the owners car, soft furnishings and clothes stink as well
