25 Human Foods That Are Safe for Dogs (And How Much)
One of the most common questions I receive from dog owners is: "Can my dog eat this?" The internet is full of conflicting advice, and it can be hard to know what to trust. The reality is nuanced. Some foods that are toxic to dogs (like grapes and onions) look harmless, while others that seem questionable (like eggs and blueberries) are genuinely beneficial. The following guide is based on current veterinary nutritional science and gives you practical, actionable guidance for 25 of the most commonly shared human foods.
A general rule of thumb: treats and extras — including all human foods — should make up no more than 10% of your dog's daily caloric intake. Always introduce new foods one at a time, and stop immediately if you notice digestive upset, hives, or facial swelling.
The Complete Safe Foods Table
| Food | Safe Amount | Key Benefits | Notes |
|---|---|---|---|
| Blueberries | A small handful (5–10 berries) per day | Antioxidants, vitamin C, fibre | Great as training treats; frozen ones are a summer favourite |
| Carrots | 1–2 baby carrots for small dogs; 1 large carrot for large dogs | Beta-carotene, fibre, low-calorie crunch | Frozen carrots soothe teething puppies |
| Cooked Chicken (plain) | 1–3 oz depending on dog size | Lean protein, B vitamins | No seasoning, bones, or skin; great for upset stomachs |
| Cooked Salmon | 1 oz per 10 lb of body weight, 1–2x per week | Omega-3 fatty acids, joint & coat health | Always fully cooked — raw salmon can carry parasites |
| Eggs (cooked) | 1 egg per day for medium/large dogs; half for small | Complete protein, amino acids, biotin | Scrambled or boiled; avoid raw egg white (blocks biotin absorption) |
| Peanut Butter | 1 tsp for small dogs; 1 tbsp for large | Protein, healthy fats, vitamin E | Must be xylitol-free — check every label; natural, unsalted best |
| Plain Greek Yoghurt | 1–2 tsp for small; 1–2 tbsp for large | Probiotics, calcium, protein | Plain only — no sweeteners, no fruit flavourings; low-fat preferred |
| Watermelon | 1–2 cubes per 10 lb body weight | Hydration, vitamin A & C, lycopene | Remove seeds and rind; rind causes GI upset |
| Apples | 1–2 slices; less for small breeds | Fibre, vitamin A & C | Remove core and seeds — apple seeds contain trace cyanide |
| Bananas | 2–3 slices; half a banana max for small dogs | Potassium, magnesium, vitamin B6 | High in natural sugar — use sparingly for diabetic or overweight dogs |
| Sweet Potatoes (cooked) | 1–3 tbsp depending on size | Dietary fibre, beta-carotene, vitamin C | Plain and cooked only; raw is hard to digest |
| Green Beans (plain) | Freely as a low-calorie snack | Fibre, vitamins K & C, manganese | Canned OK if no added salt; fresh or frozen best |
| Pumpkin (plain, canned) | 1 tsp for small; 1–4 tbsp for large | Soluble fibre — helps diarrhoea & constipation | Plain only, not pumpkin pie filling (contains xylitol) |
| Oatmeal (cooked, plain) | 1 tbsp per 20 lb body weight | Soluble fibre, B vitamins | Plain, no added sugar or milk; good for dogs sensitive to wheat |
| Plain Rice (cooked) | A few tablespoons mixed with food | Easily digestible carbohydrate | White rice is gentler on upset stomachs than brown |
| Cooked Turkey (plain) | 1–3 oz depending on size | Lean protein, phosphorus, B12 | No skin, bones, onion, garlic, or seasoning |
| Cucumber | A few slices; adjust for size | Hydration, vitamin K, very low calorie | Excellent for overweight dogs; remove seeds for sensitive stomachs |
| Mango (fresh) | A few small cubes | Vitamins A, B6, C, E; antioxidants | Remove skin and stone — the pit is a choking hazard and contains cyanide |
| Strawberries | 1–3 berries for small; 4–5 for large | Vitamin C, fibre, teeth-whitening enzymes | Remove tops; avoid canned or syrup-packed |
| Peas (fresh or frozen) | A small handful | Protein, fibre, vitamins A & K | Avoid canned peas with added sodium; not for dogs with kidney issues |
| Cooked Broccoli | No more than 10% of daily intake; small florets | Vitamin C, fibre, isothiocyanates (anti-inflammatory) | High amounts cause gas; raw is fine in tiny quantities |
| Cheese (low-fat) | A small cube as a high-value treat | Calcium, protein, B12 | Some dogs are lactose intolerant; start small. Avoid blue cheeses. |
| Cooked Beef (lean, plain) | 1–2 oz depending on size | Protein, iron, zinc, B12 | No seasoning, no onions; fat trimmed; avoid processed/cured beef |
| Courgette / Zucchini | A few slices raw or cooked | Low calorie, vitamins B6 & C, potassium | No seasoning; raw or gently steamed works well |
| Coconut (unsweetened) | A small amount — 1 tsp of flesh | Lauric acid (anti-inflammatory), supports coat health | High in fat; use sparingly; avoid coconut products with added sugar |
Foods to Never Give Your Dog
For context, here are a few foods that are genuinely toxic and must always be avoided: grapes and raisins (can cause kidney failure even in tiny amounts), onions and garlic (destroy red blood cells), chocolate (theobromine poisoning), xylitol (in many sugar-free products — causes rapid insulin release), macadamia nuts, and alcohol in any form.
A Deeper Look: The Best Options for Health
Salmon is arguably the single best human food you can share with your dog. The omega-3 fatty acids EPA and DHA reduce systemic inflammation, support joint health in older dogs, improve coat shine, and have been linked to improved cognitive function. Make it a regular addition — just always ensure it is fully cooked, as raw salmon from the Pacific Northwest can carry a fluke that causes "Salmon Poisoning Disease," a potentially fatal condition.
Plain pumpkin is the underrated hero of canine digestive health. Its soluble fibre absorbs excess water in the GI tract (helping diarrhoea) while also adding bulk (helping constipation). Keep a can in the cupboard — it is one of the safest and most effective first responses to a dog's upset stomach.
Blueberries are the easiest healthy treat to introduce. At roughly 1 calorie per berry, they are virtually calorie-free, making them ideal training treats. Their antioxidant load supports cellular health and may slow cognitive ageing — relevant research exists for senior dogs showing cognitive improvement with antioxidant-rich diets.
