My Dogs weight is around 50kg and suffers from hip dysplasia and has fluffy fur. This is of great value as a 1L I would go through every 2 months as I need to give her 5 mls every day. She has no problem injesting it as I just add it to her kibble and she eats it without fuss as yes you guessed it she is just a little fussy. This has helped her emencly with her mobility and as a bonus gives a nice shine to her fur and skin. The only downside is a slight stinky breath when they pant right in your face.
We first bought the 500ml bottle to try on our 16 year old cattle dog & it made a huge difference in her mobility & wellness. We now use that bottle to refill from out new 5 litres.
