Not Sure.... I'm not sure if there is adiffence between what you get from the vet and what you get from the store....but I have only gotten it from my vet so far...and for $10....I think it is pretty competitively priced compared to the store (in reality it is actually saving me tons...lol...cause a run to the pet store turns into a $100 event every time...which I don't have...lol)...so I would just pick it up from your vet...I bought a tubs a month ago....and I push out a little drop and let Maximus lick it...(he thinks its a treat...go figure) and it will last a long time...because they don't get much |
