Blowing pills down a dogs throat with a straw or something similar isn't a good idea since it can wind up in their lungs…
If you're hiding pills, handle them with tweezers, not your fingers: that way your dog can't smell the meds on your hands and realize what you're doing. I find peanut butter works really well for hiding pills--Ki can't spit out pills when her tongue is stuck to the roof of her mouth : ) Kraft unsweetened PB won't contribute to any dental issues. A friend took it a step further and got CHUNKY pb, she swears her dog can't tell the difference between the peanut chunks & pill fragments.
Also blue cheese or Goat Cheese/Chevre are so stinky they conceal the pill odour/taste. Just a reminder, 'tho, cheese contains a lot of calcium which will interfere with absorption of Thyroid meds if that's what you're administering.
Finally, check with owners in the Fanconi section of the forum for more Pilling Tips, they're UBER CHAMPIONs at administering pills.
