The long, pendulous ears on Cocker Spaniels are prone to ear infections if they are not cleaned on at least a weekly basis. Some Cocker Spaniels may need their ears cleaned 2-3 times per week. While playing with or brushing your Cocker Spaniel, lift the ear flap and sniff the ear. If it smells clean, it is healthy.
More importantly, though, Grand Canyon helicopters (West Rim AND South Rim) have a weight surcharge if a passenger weighs more than a specified limit. The weight limit is set by the tour operator, but it's usually either 275 or 300 pounds. So, as a general rule, passengers who weigh more than that will need to pay a weight surcharge before they're allowed to board their chopper. The amount of the surcharge is set by the tour company that's operating the flight.
The rules prescribe different weight limits according to their height and age. For an 18-year-old air hostess with a height of 152 cm, the maximum weight permissible is 50 kg while air hostesses in the age group of 26 to 30 and a height of 152 cm, the weight limit is 56 kg.
