Bone Broth for Dogs and Cats: Safe Dose Is 20% of Water

Bone broth for dogs and cats does not replace balanced food — but it has a legitimate use as hydration support and an appetite stimulus in specific situations. The safe dose is up to 20% of the animal's daily water volume in broth (example: a 10 kg (22 lb) dog that drinks 500 ml/day (about 17 fl oz, or 2 cups) can receive up to 100 ml (about 3.4 fl oz) of broth), always without salt, onion or garlic — compounds that destroy red blood cells in dogs and cats (thiosulfates, according to the Merck Veterinary Manual on garlic and onion toxicosis). What the broth actually contains after hours of simmering: collagen, gelatin and low concentrations of minerals — not complete protein or therapeutic amounts of calcium.

If the pet eats complete food and drinks water normally, the broth adds no measurable value. If the pet is convalescing, elderly or refuses water, it works as a support tool — as long as it is prepared safely.

What bone broth actually contains

When you simmer bones for hours, you mainly extract three things: collagen, gelatin and low concentrations of minerals. The amount of calcium, phosphorus and magnesium that passes into the liquid is small — much smaller than the marketing suggests. Collagen, which turns into gelatin in the broth, helps joints and skin, but it is not complete protein: it lacks essential amino acids the pet needs to maintain muscles and organs.

The real benefit is tasty hydration and appetite stimulation in convalescing pets. A dog that had surgery and is eating little? Bone broth can be the push that gets it eating again. A cat with chronic kidney disease that drinks little water? A diluted broth (no salt, no seasoning) increases fluid intake. The American Kennel Club lists digestive support and collagen intake for skin and joints among the documented benefits of bone broth for dogs (AKC — Bone Broth for Dogs). But it does not replace balanced food — it works as an adjunct, not as a nutritional base.

When broth helps (and when it is a waste of time)

It works for:

• Hydrating pets that refuse plain water (especially cats with kidney disease)
• Stimulating appetite after surgery or during convalescence
• Giving palatable support during diet transitions (changing food)
• Adding texture to a natural diet guided by a veterinarian

It does not work for:

• Replacing balanced meals (it lacks protein, fat, vitamins)
• Curing dysplasia, arthritis or joint problems on its own (the collagen concentration is too low for a therapeutic effect)
• Making up for low-quality food (broth does not fix deficiencies in the base diet)

Pet's situation	Does broth help?	Why
Refuses plain water (e.g., cat with kidney disease)	Yes	Increases hydration with no effort
After surgery or reduced appetite	Yes	Stimulates appetite through flavor
Switching food	Yes, as a complement	Palatable support during the change
Eats well and drinks water normally	No	Adds no measurable value
Diagnosed dysplasia or arthritis	No, on its own	Collagen too low for a therapeutic effect
Low-quality food	No	Broth does not fix a deficiency in the base diet

If the pet eats complete food and has no appetite or hydration problem, the broth adds no measurable value — it just becomes extra moisture. The trend of offering broth every day with no clinical reason is a waste of time and effort.

How to prepare it without creating risk

The problem with homemade broth is not the bone — it is what you add (or fail to remove). Onion, garlic, salt, store-bought seasoning and chicken bones cooked until brittle are traps. Onion and garlic contain compounds that are toxic to dogs and cats (thiosulfates, which destroy red blood cells). Excess salt overloads the kidneys. Crumbling bones turn into sharp splinters that perforate the intestine.

Safe recipe (2 liters, about 8.5 cups):

1. Use large beef bones (shank, ribs) or chicken (carcass, neck) — never thin chicken bones that have already been cooked
2. Put them in a pressure cooker with 2 liters (about 8.5 cups) of filtered water
3. Add 1 tablespoon of white vinegar (helps extract minerals)
4. Cook for 3-4 hours (regular pot) or 1.5 hours (pressure)
5. Strain well — remove ALL bone residue, solid fat and loose cartilage
6. Store in the refrigerator for up to 3 days or freeze in portions

Safe proportion: offer at most 20% of the pet's daily water volume as broth. Example: a 10 kg (22 lb) dog that drinks 500 ml of water/day (about 17 fl oz, or 2 cups) can receive up to 100 ml (about 3.4 fl oz) of broth. The rest must be plain water. Never replace the whole day's water with broth — the pet needs plain water for proper kidney function.

Is homemade bone broth safe for dogs and cats with kidney disease?

For pets with diagnosed chronic kidney disease, bone broth can help with hydration — cats with CKD drink little water, and diluted broth (1 part broth to 2 parts water) increases fluid intake. The non-negotiable condition is zero salt, onion or garlic, which are toxic to dogs and cats. Use it only with your veterinarian's approval.

What NOT to do

• Do not cook chicken bones until they get too soft — they crumble and become an intestinal perforation risk
• Do not add salt, store-bought seasoning, onion or garlic (even if the broth tastes "bland" to you)
• Do not offer broth as the main meal — it does not have enough nutritional density
• Do not keep broth in the refrigerator for more than 3 days without freezing it (risk of bacterial contamination)
• Do not offer smoked, seasoned or industrially processed broth (sausage, bacon, ham)

The ready-made alternative (and when it is worth it)

Commercial bone broth for pets exists — brands like Brutus Bone Broth and The Honest Kitchen sell freeze-dried or liquid versions formulated for animal consumption. The difference: controlled collagen concentration, no toxic preservatives, free of onion and garlic. The cost per volume is much higher than homemade, but the convenience and microbiological safety justify it for owners without the time or setup to make it at home.

If you choose the commercial option, read the label: ingredients should be only bones, water and perhaps vinegar. If you see "natural flavor," "yeast extract" or "palatant," be wary — it may be broth thickened with additives that mask low-quality raw material. And compare the cost/benefit with the effort of making it at home: homemade broth is much cheaper per liter and lasts up to 2 weeks frozen.

Frequently asked questions

Can I give my dog bone broth every day?

You can, as long as it is a small amount (up to 20% of the daily water volume) and the base diet is balanced. Daily broth makes sense for elderly dogs with arthritis or dogs recovering from surgery, but it adds no measurable benefit for healthy pets that already eat good-quality food.

Does bone broth help hip dysplasia?

Not directly. The collagen in the broth may give mild support to cartilage, but the concentration is too low for a therapeutic effect. Hip dysplasia requires veterinary management (weight control, specific glucosamine/chondroitin supplementation at therapeutic doses, physical therapy). Broth is a comfort aid, not a treatment.

Can cats have bone broth?

Yes, but with more caution than dogs. Cats are strict carnivores and need taurine, which is not present in bone broth. Use the broth only as a hydration stimulus (especially in chronic kidney disease) and never as a meal substitute. Recommended dilution: 1 part broth to 2 parts water.

How long does broth last in the refrigerator?

Up to 3 days in a closed container. After that, freeze it in portions (ice cube trays work well) — it lasts up to 3 months in the freezer. Thaw only the day's portion, and never thaw and refreeze.

Is beef bone better than chicken bone?

For broth, yes. Large beef bones (shank, ribs) yield more collagen and are safer — they do not crumble. Chicken bones (carcass, neck) work, but never use chicken bones cooked until brittle — they turn into sharp splinters that perforate the intestine.

---

Bone broth works as support — hydration, appetite stimulation, mild joint comfort in elderly pets. It is not the magic solution Instagram sells, but it has a place in the routine of owners who know what it delivers (and what it does not replace). If your pet eats well, drinks enough water and has no diagnosed joint problem, broth is optional. If the pet is convalescing, elderly or has a reduced appetite, broth becomes a practical tool — as long as it is prepared safely and offered as a complement, not as a base.
