I totally agree with comments reference too quick an attribution to Pirelli or indeed Murano, on my trips to Milan I often see lamp-workers making animals by the Canal Region just down from Porta Genova - this is an antiques and collectables part of Milan so it makes sense
I think tentative attribution or putting up for examination while we wait for examples with actual labels as some say is all we can do, in this case scenario we can study similarities and look at any provenance - see Frank's excellent post
I will be adding many more examples to my Pirelli pages and also pages of other animals to try and get identification
In the case of the items I linked to - we know the Scottie is Pirelli as it is seen with the label on the website, I purchased about 15 other pieces with it from my source, a collector buyer called Elspeth based in the Barras area of Glasgow who assured me the woman who sold her all the items together (there where many more I did not buy) were all collected in her childhood and she remembered peeling the Pirelli labels off - a tall story? perhaps and it can never be taken as proof in place of an actual label, but what I did like was the similarity in all the pieces to the Scottie and elephants etc. here is the smaller donkey I was talking about
