Heartworm plus?? I use Sentinel Spectrum as that kills most worms and flea larvae too. If you break it up and mix with food we had no GI or other issues. You have to check which worms are killed by each of the worm meds. The Sentinel Spectrum seemed to cover the most parasites, but it is expensive.
I use Frontline Plus topical for fleas and ticks. Both meds once a month, ugh!
It might be worth checking with your vet which are best for your particular dogs. |
