Each doggo is different, and our CEO Frank (a mini Dachshund) loves nothing more than using a regular size Boris as his pillow, so not necessarily do you need to match size of toy with dog. Both have all the same safety features, and are just as durable, just one is more manoeuvrable than the other.
Cat toys come in one size. Ruh oh! We do not recommend buying our cat toys for dogs, as they contain cat nip.
Boris is here as an example of sizing, diagram is for illustration purposes only. All our toys are roughly the same dimensions, within their size categories. Exact dimensions are on product pages.
