We have 3 rottie crosses - 30kg- 70kg in weight. They have been taking doggy daily for the last 6 months. Although not a great photo it shows how shiny they are. I found it surprising that they LOVE the taste - I use a bit of olive oil to stick it to the biscuits. I’ve sold the benefits to other dog owners. I am on a prescription - one large pot lasts me a month.
