Collar anti-Lobo
La Solución Innovadora para Proteger Ovejas, Bovinos y Equinos de los Depredadores Introducción Los ataques de depredadores, especialmente de lobos,
Attacks by predators, particularly wolves, on livestock (sheep, cattle, goats) are a growing challenge for farmers. There are several tools available to protect your herd effectively: guard dogs, shepherd’s aids, electric nets, electric fencing and, of course, the CAL Anti-Wolf Collar. In this article, find out how to combine these solutions for optimal herd protection.
Wolves are the predators most feared by farmers. Its attacks can cause significant losses, both in terms of sheep, cows, or other cattle, as well as stress for the animals and additional costs for the farmer.
Other animals such as bears, lynxes or stray dogs can also threaten herds. Appropriate herd protection must therefore be versatile.
Guard dogs (such as Patou or Kangal breeds) are indispensable allies. Their presence deters predators and reassures animals. They are effective for flocks of sheep.
Shepherd’s assistants play a key role in monitoring and managing herds. They can intervene quickly in the event of a threat and complement the action of other protection tools.
Electric nets and electric fences are effective physical barriers. They prevent predators from approaching animals and are suitable for all types of herds (sheep, cattle, goats).
The CAL Anti-Wolf Collar is an innovative protection tool. With its flashing lights and ultrasonic alarm, it repels predators in the event of an attack. It is easy to install, suitable for all animals (sheep, cows, horses), and complementary to other solutions.
The Anti-Wolf Collar (CAL) protects sheep, goats, cattle and horses from wolf attacks. This collar, placed around the animal’s neck, constantly monitors its behaviour. In the event of flight or panic, potential indicators of the presence of a predator, the collar activates a powerful ultrasonic alarm and flashing lights. These stimuli are designed to disorient and repel the predator, surprising it before and at the moment of attack. On average, one animal should be equipped for every eight animals.
After more than 3 years of use, in 2025, there were more than 1,300 CALs in place, covering more than 200 herds, with an effectiveness rate of over 90% (see the full results here). The CAL has proven its effectiveness as a herd protection tool. It is easy to use, robust, reliable and waterproof, offering livestock farmers an additional solution for protecting their animals.
No solution is 100% foolproof. By combining electric nets or electric fences with CAL Anti-Wolf Collar, for example, you can maximise your herd’s protection against predators. Here are some of the benefits:
• Reduced losses: Fewer attacks mean fewer financial losses.
• Less stress for animals, which improves their health and productivity.
• Flexibility: Each tool has its strengths. For example, electric nets protect fixed areas, while the CAL Anti-Wolf Collar works on the move.
‘It’s a tool you can’t do without. No single method is completely effective, so you have to combine lots of different things to protect yourself. Here, the tourist pressure is such that it’s extremely complicated to manage the dogs. CALs don’t attack tourists. I can’t say that they’re not effective.’
Emilie, farmer in Haute-Savoie
« In 2023, I had a lot of problems with wolves disturbing the cows, driving them out of the park every fortnight, making them aggressive towards me and the working dog, as well as hikers! In 2024, I wanted to try the collars. Despite a strong presence of wolves (photos of wolves in the enclosure were taken), I haven’t had a single problem with my animals. They are less stressed, and there are no more problems with animals running away and breaking out of the enclosure. It’s an excellent product that doesn’t prevent attacks 100%, but it comes close. »
