Metal dog training prongs with labeled sizes on a white background

Secret Powers Collars are available in three sizes based on the prong size inside the collar. All Secret Powers Collars are adjustable and will fit within a certain range for each size. You will also want to consider the length of fur your dog has when selecting a collar.

MEASURE TWICE AND ORDER ONCE! Proper fit is key to the Secret Powers Collar. To find the right size collar for your dog, measure high around its neck to the back of its ears. It should be snug but not too tight.

LOLA LIMITED CUSTOMERS: Sizing has changed slightly so please measure and recheck our size chart before ordering.

SAFETY 

Always supervise your dog while using a prong collar, and remove it when your dog is unsupervised. The collar is intended for supervised use when walking or training.

The Secret Powers Collar should never be left on a dog during off leash play time with other dogs.

We recommend using a prong collar under the guidance of a professional dog trainer when available to ensure the best results and avoid misuse.

While prong collars can be effective for many dogs, they are not suitable for every pet. Consult with a professional trainer when available to determine if it’s the right choice for your dog.
