I have a pup.  She is growing fast.  I bought some Panacur paste syringes a few weeks ago, but I'm a bit short now for the 3 day dosage I have to give.

However, I have loads of Panacur 10% for the older dogs....

Am I right in thinking I can give the syringes for 2 days and then the 3rd day, I could just use the Panacur 10%?  (It also says to give for 3 days and gives the dosage for pups.) 

Yep that should be fine, it's just a different presentation, only give one day of the 10% after the two of the paste syringe.

Excellent, thanks Barbara.
