BLACK line training treats contain no glycerine, which can cause digestive problems in some dogs. Each flavour is a single protein source and muscle meat only (98% meat in most flavours, 88% in the salmon variant) with 1.5% apple fibre, no offal and no fillers. They are air-dried and hard, so your dog has to chew them.
Good training treats are the foundation of effective training. For owners of dogs with allergies or a sensitive digestive system, however, finding the right treats can be a challenge. That is why in the BLACK line we have gone for a simple composition: 98% muscle meat, 1.5% apple fibre and minerals, with no glycerine.
Why glycerine-free treats
Glycerine is often used in treats because it keeps them moist and pliable. In some dogs, however, it can cause digestive problems. If your dog has a delicate stomach or allergies, it is worth looking for treats without unnecessary additives. BLACK line treats contain no glycerine.
One protein, only muscle meat
The BLACK line also stands out for its single-protein character: each flavour is based on a single protein source. This matters when you need to control an allergic dog’s diet precisely, because it is easier to avoid an ingredient that does not agree with it.
- muscle meat only, with no offal, cartilage or ground bones,
- besides the meat, only apple fibre (1.5%) and minerals or sea salt (0.5%),
- meat content according to the labels: 98% in most flavours, 88% in the salmon variant.

BLACK treats are air-dried to a moisture content of 4.8-6.4%. This gives them an intense flavour that motivates your dog to work, and they do not dirty the trainer’s hands. They are hard, so your dog has to chew them. That is what sets them apart from our Trenerki, which are soft and contain 1% glycerine and offal.
