Thanks, Jacqueline. I found it Combo-guard online at http://vethical.com/comboguard.html
Thank you for letting us know about another option. Frontline has not worked for my dogs for several years here in the East Bay, and I have concerns about Trifexis.

The introduction of spinosad for use in agriculture resulted in the receipt of a Presidential Green Chemistry Challenge Award3 in 1999 from the U.S. Environmental Protection Agency. The award was presented to Dow Agro Sciences LLC in the category of Designing Safer Chemicals for the introduction of spinosad as an insect control product for use on crops. This award demonstrates that spinosad, as a technology for insect control, has a favorable environmental profile. This award is not relevant to the safety and efficacy of Vethical ComboGuard, nor does it confer any environmental benefit to Vethical ComboGuard.

Your veterinarian will know
Your veterinarian is your best source of advice about your dog's healthcare.
Your dog should be tested for heartworm infection before starting Vethical ComboGuard.
To minimize the likelihood of fleas continuing to jump onto your dog, it is important to treat all household pets with an approved flea protection product.
If a dose is missed and a monthly interval between doses is exceeded, then immediately give Vethical ComboGuard with food and resume monthly dosing. This will minimize the opportunity for heartworm infection. Also, continuing normal monthly dosing will allow you to gain control of any flea infestation or intestinal parasite infection that might have affected your dog. Vethical ComboGuard should be administered at monthly intervals beginning within 1 month of the dog's first seasonal exposure.
Vethical ComboGuard is not for use in humans. Like all medications, keep Vethical ComboGuard out of reach of children.
Important Safety Information
Serious adverse reactions have been reported following concomitant extra-label use of ivermectin with spinosad alone, one of the components of Vethical ComboGuard chewable tablets.
Treatment with fewer than three monthly doses after the last exposure to mosquitoes may not provide complete heartworm prevention. Prior to administration of Vethical ComboGuard, dogs should be tested for existing heartworm infection. Use with caution in breeding females. The safe use of Vethical ComboGuard in breeding males has not been evaluated. Use with caution in dogs with pre-existing epilepsy.
The most common adverse reactions recorded in clinical trials were vomiting, pruritus, lethargy and diarrhea. To ensure heartworm prevention observe your dog for 1 hour after administration. If vomiting occurs within an hour after administration, redose with another full dose. Puppies less than 14 weeks of age may experience a higher rate of vomiting. "
