There is a difference...
...between 'lint' which is created during the washing process and animal hair/fur.
Front loaders, generally speaking, produce much less actual lint during washing which is why they don't have lint filters. As an example, I have just dried (ok, last night) a full load of mixed items in the dryer and got less than a tightly 'scrunched up tissues' worth of lint off the screen....
Front loaders, however, are not good at removing pet hair....that generally needs water to 'float' them off and a decent filter, such as a GE filter-flo, to catch them.
....which is part of the reason we have 'non-drop' dogs...
