Marlo has been trialled and tested on the fussiest of eaters, but we understand many dogs can be suspicious the first time you introduce anything new to their food. Therefore, we recommend halving the dose and stirring it into your dogs food or combining with a favourite snack for the first few days before increasing to the full dose. They should learn to love it! If for some reason your pup still refuses to take their vitamins, we offer a 30-day money back guarantee. Just get in touch with our customer care team for more details.
