Disclaimer: Advice given in the Home Care series of articles is not meant to replace veterinary care. When your pet has a problem, it is always best to see your veterinarian as soon as possible. But in some cases, it is not always possible to seek veterinary care. You could be traveling, it could be after hours and there are no 24-hour clinics near you, or maybe you simply can’t afford it. Whatever the reason, when your pet has a problem, you need answers. Most vets will not give you any information over the phone – they will tell you to bring your pet in for an office visit. So, when these difficult situations arise, many pet owners don’t know what to do – and they end up doing the wrong thing because they don’t have sound veterinary advice. When your pet has a problem and you can’t see your vet, the information in this series of articles can help guide you so that you will not inadvertently cause harm to your pet. However, this information is not a replacement for veterinary care.
