If you do not want your dog, you should do the following: - Figure out the reason or the reasons why you do not want to pet him, - Think about alternative solutions. For example, if a family member is allergic, instead of leaving the dog, you could consider allergy medications, - Talk to your family members including kids, and inform them about your intention, - Find a new home for your dog; you would feel more peaceful if you give your dog to someone trustful, who knows the dog and will take care of him well. - Spend some quality time with your dog before giving him away, Treat him well before leaving.
