How to serve cantaloupe

How much cantaloupe can a dog eat?
Treats of every kind should stay under 10% of a dog's daily calories, says the World Small Animal Veterinary Association. Here is that daily treat budget by size, and how much cantaloupe it buys if cantaloupe is the only treat that day. Cantaloupe has about 34 kcal per 100 g; 1 melon, medium (about 5" dia) (552 g) is about 188 kcal.
| Dog size | Daily treat budget | Max cantaloupe a day |
|---|---|---|
| Small (10 lb) | 26 kcal | 77 g (an eighth of melon, medium (about 5" dia)) |
| Medium (30 lb) | 59 kcal | 174 g (a third of melon, medium (about 5" dia)) |
| Large (60 lb) | 100 kcal | 295 g (half of melon, medium (about 5" dia)) |
| Giant (90 lb) | 136 kcal | 400 g (two thirds of melon, medium (about 5" dia)) |

Other fruit: quick answers
| Food | Verdict | Short answer |
|---|---|---|
| Avocado | Avoid | No. Avocado contains persin and is very high in fat. |
| Cherries | Avoid | No. Cherry pits, stems and leaves contain cyanide. |
| Bananas | Small amounts | Yes, as an occasional treat. Bananas are low in calories but high in sugar. |

Rules for any new food
- Plain is the rule: no salt, butter, oil, onion, garlic, sugar or sweeteners. Most of the danger in human food comes from what is added to it.
- Keep all treats under 10% of your dog's daily calories (WSAVA). The rest should come from a complete dog food.
- Check labels for xylitol, raisins, chocolate and macadamia nuts, which turn up in baked goods, snacks and spreads.
- If your dog has a health condition, such as diabetes, pancreatitis or kidney disease, ask your vet before adding any new food.
