7 month old obsessed with eating her own and our other dog’s poop – will she grow out of it?

We have a 7 month old golden retriever and as the title says she is obsessed with eating poop. No matter how much we monitor it and clean it as quick as we can, we have a huge garden and she will see our other dog pooping and be in there before we can get anywhere near. Normal recall, no matter how we try (treats, excitement, etc) is totally ignored.

We can't stop her going in the garden, it's just not fair and especially on our other dog. We are going to try supplements to make it unpleasant but she weighs nearly 20kg and our other dog is 40kg so you can imagine how much it would cost to use no poo supplements for both going forward.

Is this something she might grow out of? We hoped she would have grown out of it by now but it's getting worse if anything. If our other dog goes out and poops she will actually bark to try and get out to it to eat it…
