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.
Members of the House of Representatives must be at least 25, citizens for seven years, and residents of the states which send them to Congress. The states may set additional requirements for election to Congress, but the Constitution gives each house the power to determine the qualifications of its members.
