How to Mix Wet and Dry Dog Food
Yes, you can mix wet and dry food. Most vets recommend it. The key is getting the calorie math right so you do not overfeed or underfeed. This guide covers ratios, calories, and transition timelines.
Mixing Ratio Guide
Three common ratios and what they mean for a 30 lb moderately active dog (~600 kcal/day). Based on a wet food at 420 kcal per 13 oz can and dry food at 380 kcal per cup.
25% Wet / 75% Dry
Best for: Large dogs where cost is the priority. You still get hydration and palatability benefits.
50% Wet / 50% Dry
Best for: The sweet spot for most dogs. Equal nutritional contribution from both. Good balance of benefits and cost.
75% Wet / 25% Dry
Best for: Dogs that strongly prefer wet food, or dogs needing maximum hydration. The dry portion provides dental benefit.

Benefits of Mixed Feeding
Hydration
Even a 25% wet food ratio adds meaningful moisture to your dog's daily intake. This is especially valuable for dogs that do not drink enough water, or those prone to urinary tract issues.
Dental support
The dry kibble portion provides mild mechanical cleaning of teeth, which pure wet diets lack. Not a substitute for dental care, but better than nothing.
Cost savings
Mixed feeding costs 30 to 55% less than pure wet food, depending on the ratio and brand tier. For large dogs, this can save $60 to $150 per month.
Improved palatability
Adding wet food to kibble makes meals more appealing, particularly for picky eaters. The moisture and aroma from wet food can turn a refused kibble meal into a cleaned bowl.
7-Day Transition Schedule
If your dog currently eats only dry food, introduce wet food gradually. Start small and increase the wet portion over a week.
| Day | Dry Food | Wet Food | Notes |
|---|---|---|---|
| 1 to 2 | 90% of total | 10% of total | A tablespoon of wet mixed into kibble |
| 3 to 4 | 75% of total | 25% of total | Quarter of target wet amount |
| 5 | 60% of total | 40% of total | Approaching half and half |
| 6 | 50% of total | 50% of total | Equal split or target ratio reached |
| 7+ | At target ratio | At target ratio | Maintain your chosen ratio going forward |
Common Mixed Feeding Mistakes
Feeding full portions of both
The total calories from wet + dry combined must equal your dog's daily requirement. If you add wet food, reduce the dry food proportionally. Otherwise you are overfeeding.
Not adjusting for calorie differences
A cup of kibble and a can of wet food contain very different calories. Always calculate based on the specific kcal content of your chosen products, not generic portions.
Switching ratios abruptly
Even once you have established mixed feeding, avoid sudden ratio changes. If you want to increase the wet portion, do it gradually over 3 to 4 days to avoid digestive upset.
