Yes I couldn't agree more about their short life spans, the grief that is caused when they pass away, the amount they cost in vet and food bills, and the inconvenience when you want to go away.
BUT in a dog, a woman (or a man) could not wish for a more faithful and loving companion (whether solo or not), and to have that greeting when you walk through the door is like no other. I didn't realise this until, after the last 17 years of having dogs in my life, - the love of my life Cass a whippet finally died last July, - after my husband died 10 years ago this dog was my shadow, and it was more a case of being 'in love' with each other, rather than loving each other. Only dog owners would understand this.
Yes, I felt physically ill after his demise, and yes I have had the freedom to go places without a second thought, and not worry about the 5 hour time limit of leaving him alone, BUT I cant wait to get another dog in need of the love and companionship I have to offer - this is not to 'replace' Cass, because each animal has individual characteristics, but I'm already feeling better at the anticipation of having another dog in my life !
