There may actually be two sides to your question so I will try to answer both. If you are asking if dogs can catch a "cold" from people the answer is hardly ever. If you are asking can dogs catch a "cold" from other dogs the answer is yes. It is also important to recognize that respiratory infections are caused most commonly by bacteria or viruses. It is common for the same environmental stresses of frequent temperature change, being tired or similar situations to stress both the people and pets in a household which then allows organisms in the respiratory tract to overpopulate leading to symptoms in both the people and pets even though they did not "catch it from each other"
