This product was recommended for my cat's immune system. What dosage would you recommend. He is also in early stages of renal failure.

Many thanks

I would suggest 0.5mls of the drops twice daily for 2 weeks, then 0.25mls twice daily.

Vetri dmg - use with African Grey Parrots

12th Dec 2014

vetri dmg -can it be used with African Grey Parrots
I have read that dimethylglycine can help with seizures etc in these birds

I am not sure that this will have much effect on fits, though it has been claimed to. Certainly ultraviolet light (natural sunlight if possible, but suitable UV light bulb otherwise) is well known to help. These birds are notoriously bad at eating a balanced diet and tend to be deficient in multiple vitamins and minerals. They should be fed on a complete, balanced kibble if possible and not allowed to pick out their favourite food items from a selection of different seeds and nuts. They tend to make bad choices and suffer as a consequence. Tending to these things is much more likely to help.

What's the dosage per day ?

I am unclear on directions for a 45 lbs bulldog is It 1 or 2 times daily dosage and for how long ?? Will it make her tummy hurt cause she's sensitive it's for red mange ??

John Cousins

The suggested dose for a 45lb dog is 2 capsules twice daily for 2 weeks, then 1 capsule twice daily until the problem is resolved. I would do this until all 120 capsules have been used up (just over 6 weeks at that dose rate). At that time you should decide if it is desired to continue with another course (at 1 twice daily). If the problem has completely cleared up, then you should stop treatment. If the problem has not improved at all you should talk to your vet about a different treatment. If the problem is improving but is not yet better, than another course at 1 twice daily would be sensible.
