Like your husband, there have been times when I've really wanted to have a dog. However, I also love to travel.
I don't like the idea of kennels - both on grounds of cost but also because I was looking at rescue dogs and felt concerned that leaving such a dog in kennels might make it feel abandoned all over again.
What I've done, which works for me, is join TrustedHouseSitters.com. Based on altruism (no money exchanges hands), the site brings together those looking for house and pet sitters with those who'd like to sit.
Sitters are police checked and references are required.
Over the past two years, I've enjoyed the company of some great animals in Andalusia, Norfolk, Edinburgh and the South of France....so have had my 'fix' of both pets and travel.
Worth a look if you're concerned about the expense of kennels, or being tied down... and are happy to have someone house and pet sit...?
