There was a problem hiding this comment.
Wrong use of group_by, group_by is used for grouping items from an enumerable and return a hash. Since you are just iterating each itself can be used here.
You can also use a single each block to so this.
pets.each do |pet|
if res[pet.animal_type_id]
# ....
else
res[pet.animal_type_id] = [pet.name]
end
end
