What matters most for sensitive stomachs
A bark collar does not touch your dog’s gut directly, but the sensitive-stomach angle still matters with citronella sprays. Some dogs lick at residue or react to the scent, and a queasy dog may drool or retch if the spray is strong. For these dogs a scent-free vibration or tone collar is the gentler route, since it removes any chance of ingesting spray near the mouth.
If you prefer citronella, choose an unscented or mild formula and wipe the chin after sessions so nothing is swallowed during grooming. Watch for lip-smacking, gulping or refusing food after wearing it, as these can signal mild nausea. A sensitive tummy is often diet or stress related, so loop in your vet before adding any new device to an already unsettled dog.
