poked this one during my slow art time recently and then as a sort of warm-up after coming back from my trip and not drawing for a week :'3c

head-bumping is a show of intimacy in their culture, like kisses except extended to purely platonic relationships too, as shown here~
their dad will often go "!!!! my B O Y S" and then charge forward to smack their heads together - he tries to be gentle but is a very enthusiastic affectionate man, haha

also they're both a bit lighter here because it's winter, and their coats get fluffier and lighter in the winter and then thin out and darken a tad in the summer (this also means that family and friends tend to have nice grooming sessions where they brush the FUCK outta each other to remove all that loose fur lol)
