Whomever Theodor Holtmann was - he seems to have been a 19th-century German genre artist, and that's all I've dug up - he had a great sense of everyday life with toddlers and dogs.  This is his oil on panel Beste Freunde (Best Friends), and I love how he has not been shy to show a little kicked-off sock and bedclothes everywhere.
