Hmmmm, it's a big decision. This is the longest I've ever been without a dog since my English Bull cross Staffie died and Sparks' Cocker Spaniel died a couple of years ago. Sparks would get another dog tomorrow but they are tying, we both work long hours and love to travel. It can be as expensive to put the dog in kennels whilst you are away, as paying for your own holiday.
Although dogs take a lot of training, walking and general looking after and can be expensive :- vet bills, insurance (doesn't cover everything), food, toys, kennel fees etc. The affection and pleasure that you get from your dog more than makes up for it. I suppose it is like having another child in the house in a way, except, this kid is always pleased to see you, doesn't answer back and doesn't demand new trainers every 2 weeks..
They can be naughty in other ways though, as I found out when my dog had died...... I was clearing out under the stairs where she sometimes used to hide and I found about 30 balls (mostly tennis and rubber balls) that she had nicked from other dogs whilst we were on our walks and hidden very carefully lol...
