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.
One way that modern Tour de France bikes are âballastedâ to the 15-pound weight limit is through the addition of electronic shifting. These systems do away with potentially troublesome cables, opting instead for batteries and small motors to move the chain from cog to cog.
