Sustain Supplement for Large Breed Dogs - 30 Sachets

Keeps my dogs gut healthy

More than one of the sachets had spilled the powder contents into the box. At a price of more that £1 per sachets I would expect better packaging. This complaint lies with Sustain, not the seller.

This is great stuff. It worked in about 3 days for my dog. On the vet's advice I split his meals up so he ate 6 small meals a day with the powders on one of them, mixed into his wet food.

I've been using this product for my labrador since October 2025 after having severe stomach problems. It settled her stomach within a week of taking. I've now got my dog down to one every other day and this seems to keep her on a even keel. It's stopped the diarrhoea and sickness. Highly recommend.

I've ordered from Petplanet uk a few times and as always, fast reliable delivery, thank you so much!

About sustain this probiotic powder is a must for dogs with allergies and leaky gut syndrome especially Shar Pei.
Sustain probiotic is made from pork liver and NOT from poultry like many other brands which cause allergic reactions themselves.
I've learned this the hard way when I switched from Sustain to Purina Fortiflora because it was unavailable at the time of ordering. My boy's ears became inflamed within a week, a clear sign of an allergic reaction to chicken.
I've switched back to Sustain and Bailey is now a healthy boy again. This probiotic powder is the best I came across.
