Here’s an article from the April 14 1928 edition of the Toronto Daily Star about a woman who owned a large number of Pomeranians, which caused the neighbours to complain:
A search of the Toronto city directories reveals that the neighbours would not have had cause to complain for long: J.W. Bruce is listed in the 1928 Toronto city directory at 663 Carlaw, but is not listed in the 1929 directory. I couldn’t find him at a different address, so it looks like the Bruces moved out of town and presumably took their Pomeranians with them.
The house at 663 Carlaw still stands – it seems like a nice place, but it might have been a bit crowded with 30 Pomeranians in there.
