Collar or harness? The answer depends on the dog, the walk and the market you sell into.
Fit first. Two fingers should slide comfortably under any collar. For harnesses, the chest panel must sit behind the front legs, not on the shoulder.
Pulling behaviour. Strong pullers and brachycephalic breeds do better with front-clip no-pull harnesses — pressure moves off the trachea onto the chest.
Material. Webbing is the everyday workhorse; leather sells as a premium lifestyle SKU; padded collars protect coats during long training sessions.
For buyers: the highest-velocity retail assortment is one webbing collar, one padded collar, one no-pull harness and one matching leash in four colourways. That is exactly the skeleton of our 8-SKU launch range — available for private label with low MOQ.
