I just read some of the recent posts about "Antlerz". Nugget is a big bully stick lover, but she can devour one in 20 minutes...it gets a little pricey. So, I'm thinking about getting Antlerz with the hope that they would last longer. However, I'm wondering about the calcium in them? Nugget is fed a raw food (meat, veggies, bones combo) diet. I know when she was a pup, we had to be watchful of the calcium balance....not too much not too little. Does anyone think I should be concerned about her getting too much calcium from the chews in combination with her diet? (She's 3 now.)
