We've gotten our doxy at Walgreen's and several of our dogs are on their prescription savings program (which they allow) so we only pay about $8 for a 30 day supply. Its been a good deal for us whenever our vet prescribes human meds on the Walgreen's formulary list.
So sorry you had to say goodbye to your sweet black shy girl. We had a sweet shy black girl with some amazingly similar qualities and know the pain you are feeling and how each step was like a marathon when they learned something new. We send you healing thoughts and hope that her memories bring you smiles.
