this isn't actually mutual aid, it's more like charity work. mutual aid is a type of reciprocity, and the people being helped here don't really have anything to offer.
as with any kind of charity, it also runs the risk of developing dependence. are you going to keep walking the dog when this is over?
anarchists should actually argue that many of these activities should really be treated as labour and associated with some kind of compensation, especially in a scenario where work is likely to be scarce for a while. mutual aid is not equivalent to free labour for the bourgeoisie.
so, don't confuse misguided christian do-gooding with socialism or anarchism. this is a co-option of the language that does not align with the theory and should be opposed.
