I have used Yumega Plus for my male Labrador for some time as he suffered dry skin conditions with flakey sore looking patches. I used it for just over a year daily to get the results I have now, no more patches, I will keep using it to maintain good skin conditions.
I use on both my dogs although only one had this problem.
They enjoy the taste so no problems in giving this on the dry food I use, the cost although may seem high is well worth buying, particularly as I buy 3 bottles at a time, this saves a fair amount of money and keeps well in the dark bottles supplied.
The only problem is I find it can be messy with oil getting on my fingers and the outside of the bottle requires wiping after use.
