Frequently Asked Questions
Should my dog wear a coat in the rain UK?
Dogs with thin, single-layer coats benefit from a waterproof coat in UK rain. Breeds like Greyhounds, Whippets, and Staffies lose body heat quickly when wet. Double-coated breeds generally manage fine without a raincoat.
What size dog coat do I need?
Measure your dog’s back length (neck to tail base), chest girth (widest point behind front legs), and neck circumference. Add 2 to 3 cm for comfort and check the specific brand’s size chart, as sizing varies between UK manufacturers.
