I bought my dog a really nice rug that it can sleep on (it doesn't sleep in its small home) for about $20, it may seem expensive but it always had trouble sleeping and now it doesn't care. I placed it at the entrance of our house and it loves it, I'm thinking of buying a little bed/sofa for it so that it has a nicer place to stay, but the rug I bought a couple of months ago has been one of my best buys yet.
Her dog bed. Oh my she loves that thing. I placed it in a corner of our bedroom, which is incidentally placed right next to a heater grate. She practically lives on that thing during the winter months. It's huge so she has plenty of space for her blankie (yes, she has a blankie) and she usually brings a few toys with her as well.
The best thing that has happened to me was this guide http://www.blackburndistributions.com/blog/pet-supplements/ , as it has really helped me up with setting lines between what’s important and what’s not for my pet. It has really made me feel relaxed knowing that my pets are secure and at ease with things and healthy life includes healthy pets!
