DON'T USE IF BLACK film on product or tube after opening...product may be bad or just oxidized.
I used this for the first time today and 30 mins after using it I noticed there was black product under the cap of the tube.  I contacted Virbac maker of the toothpaste they said to send it back to them as this product should not be turning black!  They will test it once returned to see of it was oxidizing and or toxic.  I originally bought a tube of this from the vet and gave it to my sister to use, so I ordered it for me on Amazon.  The vet said it is a good product.<br /><br />Seems after speaking with the manufacturer there have been problems with some of the tubes in some of the flavors.  I will test the replacement tube and if it doesn't turn black after opening I'll use it.  My dog loved the taste!  Hopefully it was just oxidizing and not toxic for her...it didn't turn black until at least a half hour had gone by.
