Pro-Biotic dog drinks?

I went to a trade show on Sunday, and got some free samples of a pro-biotic dog drink!

The dog has 30ml per day (regardless of size of dog, which I find strange), and it can be drunk straight, or mixed with water.
It looks like chicken gravy!
It's bloomin expensive (about £3.50 per week!), but I was wondering what peoples thoughts are?

Waste of money, or worth it?

Just thinking about it because of Teagans tummy problems recently.

My vet mentioned these and I think he stocks them.
I sometimes give Tala the probiotic drinks (for humans) from the supermarket.

I've tried the probiotic granules from Pooch and Mutt and they're good, but I think you're better off and cheaper buying proper probiotic yogurt and some health food shop bran, than all these fancy ways of doing it tbh!

Haven't tried these but I got some probiotic granuals off vetuk which were great, just a spoon a day, about £7 a tub hun, might be worth a look and cleared up dodgy tums no probs

I just gave mine half a tub of pro biotic goats milk each - they loved it. I've been told it's very digestible. Only cost a couple of pounds too.

yeah mine love goats yoghurt too

Would imagine the goats yoghurt is preferable to standard yoghurt due to the lactose in cows milk.

I got T the pooch n mutt stuff but didnt find it made any diff. Stopped giving JWB completely (he would have it with his meat for dinner when we had been training for cani x) and changed from beef to AMP turkey with bone (cooked, he wont it it raw anymore!) and voila perfect poo
