My aunties dog is has been on various tablets including heart ones for quite some time now, it's no wonder she doesn't wish to take them half of the time.

But we have found that a little dish of freshly cooked liver with the tablet stuck firmly in between a piece works.

Most dogs lap up liver and it's really good for them.

I nearly forgot when giving mine his antibiotics. Luckily, I got it down with peanut butter. He loves it.

Maybe you could crush them and mix it into the food?

I either wrap in ham or crush and mix in with a bit of tinned dog food, or a very small amount of something we have had for tea.
