Alternatives to Bravecto ?

[StillMedusa]

Doggo ( nearly 1) had her Bravecto tablet yesterday. Today she has had quite bad diarrhoea. No change in her food or anything, so I'm pretty sure it's the tablet, and I have a feeling this happened last time too.
Obviously I want her to be protected as it's coming into tick/flea season.

Any reccomended alternatives (that work!) She's a double coated dog so tick hunting is pretty tricky!

I use nexgard spectra which is a monthly chew and treats most worms including lung worm, fleas and ticks.

My dog hates the Bravecto tablet so she has the Bravecto spot-on treatment that goes directly onto the skin.
