Shopping for shiba collar/accessories in Osaka

Hey people! I am going to be in Osaka next week for the last stretch of our trip and have planned to do some shopping around the Namba / Dotonbori area. We have a faboulous little shiba inu back home and would love to take back some accessories for him – I keep seeing this specific doggy collar, it is made up of these colorful textile/wool (?) baubles but haven’t seen any shops selling it on our trip so far – have any of you seen this in Osaka or know of a specific store or chain that sells stuff like this? I can google a photo but I am not sure what the rules are on sharing random pictures.

Any tips or ideas would be appreciated!
