Can a Cocker Spaniel fly in the cabin?

Unlikely: a Cocker Spaniel at 30 lb (the top of the AKC standard) is heavier than any carrier we track is rated for, and clears 1 of the 43 published weight caps. A lighter dog may still fit. The AKC breed standard puts the Cocker Spaniel at 25-30 pounds (male), 20-25 pounds (female) and 14.5-15.5 inches (male), 13.5-14.5 inches (female) tall. Your own dog may be lighter or heavier than the standard, so weigh it in its carrier before you book.
