Glad to see it's an easy fix, seeing blood in urine would have scared the heck out of me.
when I have to give pills, tablet or capsules I use Greenie Pill Pockets. I buy the capsule size package, if it's a pill or tablet, I cut the greenie in 1/2, Pop in the pill, dogs gets their med, no fuss, it's taste like a treat. Pill giving made easy. If you haven't tried the Greenie pill pocket I suggest to do so, better then stuffing meds in pieces of salty hotdogs or sticky peanut butter or heaven forbid, last resort, stuffing down pups throat
which I had done more times then I care to remember,all before the Greenie Pill Pocket came out.
