flea & tick / heart worm for sensitive tummies

[Haley, Yeti, and Phin]

We are about out of Yeti’s last 6 mo supply of flea and tick and heat worm medicine. Curious what people give their puppies with sensitive tummies.

[Karen, Jasper and Jackdoodle]

As you know, Jack had IBD, so he could not have any kind of flavored chews. I ordered plain Heartgard tablets from Pet RX Direct (your vet can fax or email the prescription) for heartworm, and I used Frontline Plus topical for fleas/ticks. 

[Jane, Guinness and Murphy]

I use Frontline Plus and Revolution which are both topical because of Murph's IBD.
