There are many circumstances where the use of drug or fluid therapy are not sufficient and blood transfusion may be critical. Traditionally, blood and blood products have been collected and distributed from pound and shelter animals. There are community concerns about the ethical and welfare issues surrounding collection of blood from animals, particularly where there has been no owner consent. There are particular welfare concerns for animals reared solely for this purpose, as they may not have opportunity for socialisation and other care. Collecting blood from animals, including cats or dogs may adversely affect donors and steps need to be taken to ensure minimal impact.
Blood transfusion is to the benefit of the welfare of the recipient.
Surrendered animal in pound euthanased and blood collected, with consent from the owner for both procedures. In this case, it is preferable for the animal to be sedated or anaesthetised, for ease of collection. Sedation or anaesthesia should be carried out only by a registered veterinary surgeon. Blood should be routinely collected and available for clinical treatments at short notice. The collection and administration of blood for clinical treatment may be governed by specific legislation requiring, for example, specific animal ethics committee approval.
