The practical guidance in this article draws on the expertise of Fiona Whelan, Head Behaviourist at our Pet Centre in Chertsey, Surrey<\/a>. Fiona has worked with thousands of scavenging dogs over her 20+ year career and understands which solutions work in real-world situations.<\/p>\n This guide explains why dogs scavenge, which muzzles are most effective for preventing it, and how to introduce a muzzle so your dog accepts it happily.<\/p>\n Scavenging is a deeply ingrained canine behaviour. Dogs evolved as opportunistic feeders, and the instinct to grab available food remains strong even in well-fed pets. Understanding why your dog scavenges helps you address the behaviour effectively.<\/p>\n For dogs, finding and consuming food in the environment is natural behaviour – not naughtiness. Their ancestors survived by scavenging, and this drive remains hardwired. A dog who hoovers up discarded chips or investigates dead animals is simply following instincts that once kept their species alive.<\/p>\n One of the most common – and most distressing for owners – forms of scavenging is coprophagia: eating faeces. Dogs may eat their own droppings, other dogs’ faeces, cat litter contents, or wildlife droppings like fox or rabbit poo. While unpleasant, this behaviour is surprisingly common and can stem from various causes including dietary deficiencies, attention-seeking, boredom, or simply finding it palatable.<\/p>\n Some dogs go beyond food scavenging to eat non-food items: rocks, sticks, fabric, or rubbish. This behaviour, called pica, can be particularly dangerous as these items can cause intestinal blockages requiring emergency surgery. Dogs with pica need careful management to prevent serious harm.<\/p>\n Scavenging isn’t just unpleasant – it poses genuine health risks that every owner should understand.<\/p>\n Poisoning: <\/strong>Discarded food may contain toxic ingredients like chocolate, xylitol, onions, or grapes. Rodent poison bait, slug pellets, and contaminated food waste can all cause serious illness or death.<\/p>\n Gastrointestinal upset: <\/strong>Eating rotting food, faeces, or unfamiliar items commonly causes vomiting, diarrhoea, and stomach pain. Repeated episodes can lead to chronic digestive issues.<\/p>\n Intestinal blockages: <\/strong>Rocks, bones, fabric, and other non-digestible items can cause blockages requiring emergency surgery. These can be life-threatening if not treated promptly.<\/p>\n Parasites and infections: <\/strong>Faeces from other animals can transmit parasites like roundworms, tapeworms, and giardia. Wildlife droppings may carry diseases including leptospirosis.<\/p>\n Dental damage: <\/strong>Chewing rocks or bones can crack teeth, leading to painful infections and expensive dental work.<\/p>\n A muzzle provides a physical barrier that prevents your dog from picking up and eating items on walks. While it doesn’t address the underlying behaviour, it protects your dog from immediate harm while you work on training – or provides ongoing management for dogs whose scavenging proves resistant to modification.<\/p>\n Not all muzzles are equally effective for scavenging prevention. Standard basket muzzles allow dogs to pant, drink, and receive treats – which means there are gaps in the basket. For dogs targeting larger items like sticks or stones, a standard basket muzzle may be sufficient. However, for dogs eating faeces or small food items, these gaps can still allow access.<\/p>\n This is why muzzles with anti-scavenge guards exist. These guards create an additional barrier that prevents dogs from pressing their nose through gaps to access items on the ground, providing more comprehensive protection for determined scavengers.<\/p>\n Two muzzles in the Baskerville range<\/a> feature anti-scavenge guards specifically designed for scavenging dogs: the Classic and the INVISA.<\/p>\n The Baskerville Classic<\/a> is the go-to muzzle for scavenging prevention. It features a removable anti-scavenge guard that creates a barrier across the bottom of the muzzle, preventing dogs from accessing items on the ground even when pressing their nose down.<\/p>\n As Fiona Whelan, our Head Behaviourist, explains: “If the reason you’re using a muzzle is to prevent scavenging, I’d recommend one with a scavenge guard. The Classic has this extra piece so even if your dog squishes their nose into something, they still can’t actually get it. For coprophagia, the Classic would definitely be my number one choice.”<\/p>\n The Classic is particularly well-suited to dogs with narrower or longer noses and features a padded noseband for comfort. The guard is removable, so you can take it out if your dog needs the muzzle for other purposes where scavenging isn’t a concern.<\/p>\n Key features: Removable anti-scavenge guard, padded noseband, ideal for long-nosed breeds, prevents food scavenging, coprophagia, and wound licking.<\/p>\n The INVISA also features a removable anti-scavenge guard, making it effective for scavenging prevention. Its transparent design allows people to see your dog’s face, which can reduce the negative reactions muzzled dogs sometimes receive.<\/p>\n The INVISA<\/a> is the lightest muzzle in the Baskerville range, weighing just 50g in Size 1 up to 220g in Size 6. It includes 360-degree padding for superior comfort during extended wear, making it ideal for long walks where scavenging opportunities are plentiful.<\/p>\n Key features: Removable anti-scavenge guard, transparent design, 360-degree padding, lightest in range, V-shaped strap system, reflective stitching for visibility.<\/p>\n Choose the Classic if: <\/strong>Your dog has a longer or narrower nose, you want maximum scavenging protection, or you’re less concerned about the muzzle’s appearance.<\/p>\n Choose the INVISA if: <\/strong>You want to reduce muzzle stigma with the transparent design, your dog needs maximum comfort for long walks, or you prefer the lighter weight.<\/p>\n Both muzzles are made from durable TPR material that can be reshaped with hot water for a custom fit. If reshaping a muzzle for a scavenging dog, keep the anti-scavenge guard in place while moulding to ensure the fit works with the guard installed.<\/p>\n The Baskerville Ultra<\/a> and Wide Fit<\/a> are excellent basket muzzles, but they don’t include anti-scavenge guards. For dogs who scavenge larger items like sticks, stones, or substantial food waste, these muzzles may provide sufficient protection – the basket prevents picking up anything of significant size.<\/p>\n However, for dogs targeting faeces, small food items, or anything that could be accessed by pressing their nose through basket gaps, muzzles with guards offer more reliable protection. If your dog is a determined scavenger of smaller items, the Classic or INVISA with their guards will be more effective.<\/p>\n A muzzle only works if your dog will wear it calmly. Forcing a muzzle onto an unwilling dog creates stress and resistance, making walks unpleasant for everyone. Proper muzzle training takes time but results in a dog who accepts – even welcomes – their muzzle.<\/p>\n The key principle is building positive associations. Your dog should learn that the muzzle predicts good things: treats, walks, and enjoyable experiences.<\/p>\n Stage 1 – Sight association: <\/strong>Hide the muzzle behind your back with treats ready. Bring the muzzle into view and immediately give a treat. Repeat until your dog shows happy anticipation when the muzzle appears. Intersperse with bringing out an empty hand – no muzzle, no treat. Your dog learns that muzzle = reward.<\/p>\n Stage 2 – Nose insertion: <\/strong>Smear the inside of the muzzle with something delicious – cream cheese, peanut butter, or p\u00e2t\u00e9 work well. Add small treats that stick to the coating. Cup the muzzle in your hands so your dog must insert their nose to access the food. Let them approach and withdraw freely; never force. If they try to lick from outside, calmly reposition.<\/p>\n Stage 3 – Wearing duration: <\/strong>Once your dog willingly inserts their nose, gently fasten the strap while they eat. Remove it before they’ve finished the food and while they’re still relaxed. Gradually increase wearing time. Cream cheese in a tube is helpful here – you can squeeze more through the muzzle without removing it.<\/p>\n Stage 4 – Different environments: <\/strong>Practice in various locations around your home and garden before taking the muzzle on walks. Your dog should see wearing the muzzle as normal routine, not something that only happens in specific circumstances.<\/p>\n Only once your dog is completely calm and happy wearing the muzzle should you use it for walks. Rushing this process creates negative associations that undermine the training.<\/p>\nWhy Dogs Scavenge: Understanding the Behaviour<\/h2>\n
