I bought a little pitcher plant (Sarracenia) approx 8 months ago. It
was only around 4 inches high and in a 3 inch pot. It grew some so I
put it in a six inch pot. It seems to like the South facing window, not
that there are many flies for it to digest, especially at this time of
year.

However, it is putting on a vigorous spurt of growth at the moment. The
Internet says such plants generally die back over Winter. It is now 20
inches high! If it grows much bigger I fear it will eat the dog.

A little Googling reveals there are several varieties. There is one
apparently that grows to a metre high that looks suspiciously like my
pitcher plant with predominantly green pitchers and red tints around
the head and flap.

Surely that variety would not be sold as a house plant? Or would it? It
will soon be too big to keep on the window ledge.

Sounds as you should keep it outside to ward off unwelcome guests :-))
