Quick answer
Measure your dog's back length from the base of the neck to the base of the tail, then compare it with the brand's size chart. For Cocopup London raincoats, a snug but not tight fit with enough room for movement is ideal.
Why sizing matters for raincoats
A raincoat that's too small will restrict your dog's movement and may leave parts of the body exposed to the rain. A coat that's too large can drag on the ground, get caught on objects, or allow water to seep in through the openings.
Cocopup London raincoats are unlined pac a mac style, meaning they are lightweight and designed to be worn over your dog's fur. This style fits differently than lined winter coats, so it's important to measure carefully and consider your dog's fur thickness.
Understanding size charts
Most dog raincoat size charts use back length as the primary measurement, often along with chest girth and neck circumference. Since each brand may have slightly different sizing, always refer to the specific brand's chart rather than relying on your dog's weight alone.
For Cocopup London raincoats, the available option is size, so you'll need to choose based on your dog's measurements. If your dog falls between sizes, consider the fit you prefer: a slightly larger size allows for more freedom of movement, while a smaller size provides a more streamlined fit.
Trade-offs in fit
A looser fit can accommodate a fluffy dog or allow for a thin sweater underneath on colder days, but it may also let rain in at the neck and belly. A tighter fit offers better waterproofing but can be uncomfortable if your dog has a thick coat or is between sizes.
For puppies or growing dogs, choosing a slightly larger size can extend the life of the coat, but be aware that it may not fit perfectly right away. For adult dogs, prioritize a precise fit over future growth.
Decision rules for choosing the right size
- Measure back length: Use a soft measuring tape to measure from the base of the neck (where the collar sits) to the base of the tail. This is the most important measurement for raincoat sizing. Keep your dog standing straight for an accurate measurement.
- Check chest girth: Measure the widest part of your dog's chest, usually just behind the front legs. This ensures the coat can fasten comfortably without being too tight. Add a couple of inches for comfort if your dog is between sizes.
- Compare with size chart: Use the brand's size chart to match your dog's measurements. If the chart is not available, contact the seller or use a general guide based on back length. When in doubt, choose the larger size for more freedom of movement.
- Consider fur thickness: If your dog has a thick or fluffy coat, size up to ensure the raincoat isn't too snug. For short-haired dogs, a more fitted size works well. A raincoat that's too tight can cause chafing and discomfort.
- Test the fit: After putting on the coat, check that you can fit two fingers between the coat and your dog's body. Ensure the coat doesn't restrict movement or drag on the ground. Watch your dog walk and run to confirm the coat stays in place.
