Can you obtain Potassium Citrate granules for me to buy for my Pekingese? They are prescribed for him for bladder crystals. The brand name is Gold Vet and they are available at Landco, a division of Golden crown Corp., Post Falls Idaho 83854, telephone 1-800-356-4029. I get it in a 300 gram tub. it is for sale by licensed veterinarians only. I would rather buy it from you than from my vet, because I think he charges too much for it. Thank you. Bonnie Ruff
