This depends on two factors: - what product and when they had it.
For specific advice please email us at hello@tails.com and we’ll be able to advise you.
In general, you should apply our tails.com flea and tick treatment at least 48 hours after any other topical treatment, and our worm treatments should be applied at least 2 weeks after any other worm medication.
ONLY USE IF CUSTOMER MENTIONS FRONTLINE SPECIFICALLY
Frontline contains the same active ingredients as our flea treatment. So if <dog's name> has already had Frontline applied, we advise you to wait a further two weeks before applying our treatment as well and if it's required, as most flea medication only needs to be applied every month.
If in doubt we recommend you speak to your vet.
