Cardiac products are bought by two very different customers: the owner of a senior dog whose vet has heard a murmur, and the owner of a dog that is simply slowing down. Both are legitimate markets; only one of them sits next to a prescription, and the copy has to respect the difference.
| Buyer | What prompted the purchase | What the product has to be |
|---|---|---|
| Post-diagnosis owner | A veterinary diagnosis, medication, a recheck schedule | Clearly supportive, never a substitute; documentation matters |
| Senior-dog owner | Reduced exercise tolerance, a cough, "just slowing down" | Daily-use formula with credible actives and palatability |
Cardiac disease is diagnosed by examination and imaging. A supplement supports normal function; it does not treat heart failure, and packaging that implies otherwise creates both compliance exposure and unhappy customers.
| Active | Why it appears | Specification point |
|---|---|---|
| Taurine | Recognised as conditionally essential in dogs; deficiency has been associated with cardiac change in some diets | Level per serving, and the retained level after processing |
| L-carnitine | Commonly paired with taurine in cardiac support | Declare the active level; the salt form changes the calculation |
| Omega-3 fatty acids | General cardiovascular and condition support | Oxidation control in long-shelf-life products |
| Coenzyme Q10 | Widely used antioxidant positioning | Poor solubility; delivery system matters more than the headline number |
| Magnesium and B vitamins | Supporting nutrients in multi-active formulas | Levels within safe ranges — over-supplementation is not benign |
| Hawthorn and botanical extracts | Traditional cardiac positioning in natural ranges | Standardised values, and market-by-market regulatory status |
| Format | Fit | Note |
|---|---|---|
| Chew tablets | Precise dosing; the format buyers default to | Unit size limits payload when several actives are combined |
| Soft chews | High acceptance in dogs; good for daily use | Heat exposure affects CoQ10 and omega-3 |
| Oral dissolvable film | Fast intake; useful for dogs that refuse solids | Lower payload per unit — suited to focused formulas |
| Oral liquid | Easy for older dogs and multi-dog homes | Emulsion stability for oil-based actives |
Our cardiac range spans a heart care chew tablet, a heart care soft chew and a heart care oral dissolvable film. Formats are described under pet supplement tablets and pet oral dissolvable films.
Cardiac support is a long-term daily product used across a very large weight spread — from a 5 kg breed to a 45 kg working dog. Three approaches work, and one does not:
| Approach | How it performs |
|---|---|
| Weight-banded dosing table | Simple, defensible, easy to translate; the usual best choice |
| Two unit strengths | Works well where tablet size already limits the payload |
| Powder with a graduated scoop | Scales continuously, which suits large dogs and multi-dog homes |
| Single fixed dose for all weights | Under-doses large dogs and over-doses small ones — avoid it |
Whichever route you choose, the dose should be stated per body weight in the specification and repeated in the on-pack instructions, so the veterinary practice the owner consults can see exactly what is being given.
Cardiac products are usually long-term purchases for an ageing animal, so the documentation request is part of the specification rather than an afterthought:
Suppliers who can supply all four are usually the ones who can also adjust a formula when a market objects to a specific active — which is the capability that matters once a range is selling in more than one country.
No, and no product should suggest it does. Medication and monitoring are managed by a veterinarian; a supplement sits alongside that plan.
It is poorly water-soluble and sensitive to processing. The delivery system — oil carrier or emulsified powder — determines how much is actually absorbed.
Target actives and levels, preferred format, serving size, packaging format and expected order volume.
