Last time one of my client's checked, they found the cheapest source to be Target but that was for a larger dog and it was last year.

Sorry your dog has such problems. Hope you can get what he needs.

I see on Costco's web page it is just under $35. I went into my Mom's Part D plan and used the online Rx tools for you. I put in Sams Club, Target & one of our local grocery store to compare. They were from $20.76 - 21.41 for 30 days. You might even get a better price for a 90 day supply.
