Growlers in general are not meant to carbonate in as they are not designed for the pressures of carbonation, only for storage of already carbonated beer. They can explode!
If these are larger Grolsch style bomber bottles then they are fine to carbonate in as the glass is much thicker. It is also important to be sure the rubber gaskets are in good condition and form a very tight seal or the CO2 will simply escape.
