Heat stroke is perhaps one of the most common causes of heavy dog panting that can lead to devastating damage to the dog's physical health. If a dog is left in a parked car on a hot summer day, or has been out playing or running for a long time in the heat, he can easily get heat stroke.
Article I, Section 2 of the U.S. Constitution prescribes three qualifications for representatives. Like senators, there is an age qualification, but it is lower -- you need to be at least 25 to be a representative. The citizenship qualifications are also slightly less stringent -- you only need to be a citizen for seven years.
The formal qualifications for a U.S. Senator require that a candidate be at least 30 years of age, a citizen of the United States for at least nine years and be a resident of the state in which he is running. Informal qualifications for both positions are more important in today's political landscape.
