The dog farted. Yes really she did!
Get any group of Boston Terrier owners together and the jokes will turn to how gassy these cute little dogs can be.
So why exactly are Boston Terriers so gassy?
The primary reason is because of eating bad food. The secondary reason will be because squishy face (brachycephalic) dogs have a predisposition to gas.
Other reasons could be that your dog eats too fast and swallows air or there is something else going on like having parasites inside them.
