💢 September is Animal Pain Awareness Month 💢
September is Animal Pain Awareness Month, proclaimed by the International Veterinary Academy of Pain Management (IVAPM), and I’m delighted to be joining in by raising awareness in my own little corner of the canine world. This is the second in our series of posts
🟢Not Interested in Dinner? It Could Be Pain.
Lack of appetite in dogs is often misattributed to fussiness or age—but a sudden or gradual reduction in appetite may, in fact, be an early behavioural sign of pain. Pain-induced changes in feeding behaviour are particularly common in cases of chronic musculoskeletal conditions such as osteoarthritis (OA), spinal discomfort, or visceral pain (Mathews et al., 2014).
🟢 Pain affects feeding drive by altering neurochemical pathways related to stress, inflammation, and mood (Watanabe et al., 2016).
🟢 Dogs experiencing chronic discomfort may avoid positions associated with pain—such as lowering the head to a food bowl or climbing stairs to reach a feeding area.
🟢 Inappetence may also reflect referred pain from dental issues, cervical discomfort, or abdominal inflammation, which can inhibit chewing or swallowing (Lascelles et al., 2012).
🟢 Particularly in older dogs, reduced appetite may coincide with subtle signs of osteoarthritis, including restlessness, stiffness, or reluctance to be touched (Belshaw et al., 2020).
🩺 Behavioural changes like appetite loss should never be dismissed as mere aging. If your dog is “off their food,” it may warrant a pain assessment and a visit to your Vet.
Early intervention can reduce suffering and restore quality of life.
