After sunny day, where the temperatures are above 0 °C, dry snow starts to change the structure, becomes heavy and wet (starts melting). This type of snow does not stick to the dogs' coat anymore, nor to the feet. The walks become longer and more fun for everybody.
Kala also tried to make Heidi to play like she plays with May, and now with Drobižek, but Heidi got really mad twice (she barked at Kala really angry - who would not), so Kala leaves her now and bothers just the small Drobižek. However, Kala and Heidi do play together, just not in the wild Kala's style.
