Golden retrievers can supplement calcium by eating shrimp skin, but the effect of calcium supplement is not very obvious. In addition, seafood foods are relatively salty, which can easily cause kidney problems in dogs. Moreover, many dogs are not interested in seafood with high protein content. For those with food allergies, it is recommended that pets use animal-specific calcium powder or liquid calcium for calcium supplementation, which not only has better absorption effects, but is also healthier.
