Søren is a wolfdog (45% wolf with DNA test) and has a strong instinct to gain weight as soon as temperatures start to drop, but he only puts on 2 kg ; is that enough to tip into the overweight category? He loses the weight by summer as his testicles shrink and his coat starts feeling like an old broom.
