Great probiotic at a great price Anon on 1 July 2024

My dog has been on this probiotic for the past 8 months or so and I usually get it from my vets. I saw that PetPlanet carried the same product and it was about 5 cheaper than my vets. So I was very pleased to find.

Fantastic product davidpbower on 20 March 2024

Superb probiotic, our Labrador Lily was prescribed this during recovery from a severe adverse reaction to Metacam. When we stopped it after 4 weeks she wasnt right so weve kept her on it. Its a bit pricey at 1 a day but well worth it for the benefits gained.
