# The veterinary reading list

> Veterinary reading list — Peptide for Paws — The Peptide for Paws reading list brings together dog paw-pad and walking studies, feline diabetes trials and the animal-drug guidance used on this site.

The paw-pad paper is the oldest curiosity here. The walking and feline diabetes trials take the story into quite different animals and outcomes.

## Dog studies

Start with [Swaim and colleagues’ dog paw-pad wound study](https://pubmed.ncbi.nlm.nih.gov/8669775/) and [Dobenecker and colleagues’ oral collagen study in dogs with osteoarthritis](https://pubmed.ncbi.nlm.nih.gov/39298537/). I value the distance between their questions: tissue in an experimental wound on one side, movement in dogs with naturally occurring disease on the other.

The [BPC-157 preclinical safety paper](https://pubmed.ncbi.nlm.nih.gov/32334036/) and [rat-and-beagle pharmacokinetic paper](https://pubmed.ncbi.nlm.nih.gov/36588717/) describe laboratory work. The [TB-500 paper in horses](https://pubmed.ncbi.nlm.nih.gov/23084823/) develops a doping-control method. None supplies a treatment result for a pet dog with arthritis.

## Cat diabetes studies

The [newly diagnosed cat trial](https://pubmed.ncbi.nlm.nih.gov/26700409/) and the [remission-maintenance trial](https://pubmed.ncbi.nlm.nih.gov/40105430/) are the central pair. The [placebo-controlled study in obese client-owned cats](https://pubmed.ncbi.nlm.nih.gov/27136422/) supplies additional adverse-effect context. I’d read the population and outcome before deciding how to connect the papers.

## Animal-drug guidance

The [animal-drug approval process](https://www.fda.gov/animal-veterinary/animal-health-literacy/idea-marketplace-journey-animal-drug-through-approval-process), [label-status guide](https://www.fda.gov/animal-veterinary/unapproved-animal-drugs/how-can-i-tell-if-drug-legally-marketed-animals), [animal-drug questions](https://www.fda.gov/animal-veterinary/safety-health/frequently-asked-questions-about-animal-drugs), [extra-label regulations](https://www.ecfr.gov/current/title-21/chapter-I/subchapter-E/part-530) and [side-effect reporting guide](https://www.fda.gov/animal-veterinary/report-problem/how-report-animal-drug-and-device-side-effects-and-product-problems) explain the veterinary setting around the research. The [FDA’s concerns about unapproved animal drugs](https://www.fda.gov/animal-veterinary/unapproved-animal-drugs/fdas-concerns-about-unapproved-animal-drugs) include the missing reporting obligation that makes a quiet record hard to interpret.

Approval and search statements on this site are tied to checks dated September 30, 2026. These records are snapshots; later changes require a fresh check. The [animal-drug database](https://animaldrugsatfda.fda.gov/adafda/views/#/search) and [minor-species Index](https://www.fda.gov/animal-veterinary/minor-useminor-species/index-legally-marketed-unapproved-new-animal-drugs-minor-species) are separate records.

At Peptide for Paws I follow published veterinary research back to the animal on the ground; these essays offer no medical advice, and a pet’s medicine belongs with its veterinarian.
