Caring for your dog. The four main jobs of caring for a dog are feeding, grooming, taking the dog out and training it. Take the time to learn all you can about the the dog you are adopting. Learn about their behavior based on breed and history. Remember, dogs cannot be left alone for several days. They need to be fed and walked every single day. Dogs will let you know if they are hungry, but it is harder to tell if they are thirsty. Make sure that fresh water is available to your dog at all times of day. Try our BPA Free - Dog Water Bottle. For dogs and owners on the go check out our Thirsty Dog Portable Water Bowl.
