Hi!
Do you have a companion piggy? If yes, then homemade 'poo soup' (i.e. live healthy guinea pig gut microbiome transfer) is a lot more effective than any probiotic because what is transferred is
exactly what your piggy needs! It mimics natural behaviour in recovering guinea pigs - and it is conveniently free and at all times available...
Please be aware that probiotics are not classed as a medication but as a food supplement; as such vets do not necessarily prescribe it. The effectiveness of probiotics is still not entirely proven.
Here is our link with the recipe for soup and the usual support products for guinea pigs:
