The recipe for a better coat
You can see a dog's diet on its back. A coat that has gone dry, brittle or slow to regrow is telling you which nutrient ran short.
Why this bowl is built this way
Hair is protein. Roughly a third of a dog's daily protein intake goes to skin and coat turnover, and a bowl that is short on quality animal protein produces hair that grows thin and breaks. The first fix for a dull coat is not a supplement — it is enough protein from a digestible source.
The shine itself is fat. The lipid layer that makes a coat reflect light is built from omega-3 and omega-6 fats, and the dog cannot make the omega-3 ones. Egg yolk, fish oil and a little animal fat do more visible work in four weeks than any coat spray.
What goes in — by share of the bowl
Shares, not grams. The gram column is per kilogram of finished food, so it scales to any batch you cook. Your dog's actual portion comes from the calculator, because it depends on body weight and not on the recipe.
| Component | Share | Per 1 kg | Notes |
|---|---|---|---|
| Quality protein — chicken, beef, egg, fish | 45% | 450 g | Cooked. Egg counts as protein, not as a treat. |
| Carbohydrate — rice, oats or sweet potato | 24% | 240 g | Oats if the dog tolerates them; they add biotin. |
| Vegetables — carrots, spinach | 18% | 180 g | Cooked and chopped. Spinach brings iron and folate. |
| Added fat — fish oil plus one egg yolk | 8% | 80 g | The visible difference in this recipe. Keep the oil cold. |
| Veterinary completer | 5% | 50 g | Brings the zinc and vitamin E the coat needs and plain food lacks. |
Method
- Cook the protein plainly; if you use egg, scramble it without fat or add the yolk raw to the cooled bowl.
- Cook oats or rice in plain water until soft.
- Chop and cook the vegetables; spinach should be wilted, not raw.
- Add the fish oil off the heat.
- Feed for four weeks before judging. Coat turnover on a healthy dog takes that long — nothing visible happens in week one.
What each part is doing
| Part | Job |
|---|---|
| Animal protein | Keratin, the material the hair is made of. |
| Fish oil | EPA and DHA build the lipid layer that produces shine. |
| Egg yolk | Biotin and fat-soluble vitamins, in the form dogs absorb best. |
| Zinc | Deficiency shows up as a dull, crusty coat before anywhere else. |
How much to feed
Per day, for this type of dog. Two meals a day is standard for adults; puppies and dogs recovering from stomach trouble do better on three or four smaller ones.
| Dog weight | kcal / day | Food / day | Per meal (2×) |
|---|---|---|---|
| 5 kg (11 lb) | 374 | 288 g | 144 g |
| 10 kg (22 lb) | 630 | 484 g | 242 g |
| 20 kg (44 lb) | 1059 | 815 g | 407 g |
| 30 kg (66 lb) | 1436 | 1104 g | 552 g |
| 40 kg (88 lb) | 1781 | 1370 g | 685 g |

What to watch for
- Raw egg white binds biotin, so if you use whole raw eggs regularly, cook them. The yolk alone is fine raw.
- A dull coat with weight loss, drinking more water, or a pot belly is not a coat problem. That combination is a vet visit.
- Coat supplements sold as 'show shine' are mostly fish oil at three times the price. Compare the EPA and DHA per capsule, not the label name.
