Senior dogs come in very different sizes, so this family separates large-breed and small/medium-breed choices while the detailed evidence must stay tied to the selected bag.

The IAMS Senior Dog with Chicken family includes large-breed and small/medium-breed 12KG options. Detailed label information here applies to the large-breed food for dogs aged seven years and over. That recipe declares 25% dried chicken and turkey, including 15% chicken, plus 10% fresh chicken. Barley, maize, maize flour, pork fat, 2.5% dried beet pulp, chicken gravy, linseed and 0.2% fructooligosaccharides are also listed. The large-breed analysis states 25% protein, 10% fat, 2.5% crude fibre and 6.3% crude ash, with calcium at 1.3% and phosphorus at 1%.

Keep the label figures with the large-breed option. The detailed composition, analysis and feeding table presented here are verified for the 12KG large-breed food. The small/medium-breed 12KG option is part of the same senior chicken family, but its exact detailed label is not presented here and should not be assumed identical. For the large-breed recipe, the rough daily guide runs from 295g at 25kg to 775g at 90kg; adjust for the individual dog, introduce over four days and provide fresh water.
