Two problems with dogs as compared with cats, include the need to be walked at least twice a day, rain or shine, and they bark.
I love the way cats don’t need to go outside – they can be perfectly content to use a litterbox and hand around on your couch and windowsills. But dogs need to be taken outside at least twice a day, more if you have the time and opportunity. They need more of your attention, and some dogs have a problem controlling their barking, which makes if very hard on the neighbors.
But when you come home after a long bad day, a dog’s wagging tail and devout loyalty can make up for any inconveniences. A dog can truly be your best friend, for years and years of companionship.
