Why a whole hot dog overwhelms a 7 kg body
That single link likely contained 500+ mg sodium—nearly double your terrier's daily limit. Unlike gradual intake from kibble, this salt bomb hits the bloodstream all at once. Within an hour, you may notice frantic water drinking as the body tries to dilute the sodium surge.
The hot dog's rubbery texture adds mechanical risk. Swallowed whole, it may lodge at the stomach's exit, causing painful bloating. Watch for restless pacing, unsuccessful vomiting attempts, or a tense abdomen—these suggest a physical blockage developing.
Fat content versus salt toxicity
While the salt is the immediate threat, the hot dog's 15+ grams of fat pose secondary risks. In a small dog, this much fat at once can trigger pancreatitis—a painful inflammation starting 24-48 hours later. Early signs include a hunched back or reluctance to move.
Don't offer fatty foods to 'coat the stomach'—this worsens the problem. Stick to small amounts of plain boiled chicken or rice if vomiting persists beyond 4 hours. The other dogs need no dietary changes unless they stole other high-fat foods.
Checking the uninvolved dogs efficiently
Unless they're showing unusual interest in water bowls or seem lethargic, your other dogs likely avoided the hot dog. Do a quick mouth check—sometimes dogs hide stolen food in cheek pouches. Feel their bellies for unusual firmness compared to normal.
Focus observation on the terrier, but note if the others start copying his water-drinking behavior. Some dogs mimic sickness signs due to stress. Separate them during monitoring to avoid false alarms.
Emergency signs specific to small breeds
Terriers often mask distress until it's severe. Subtle changes matter most: if his bark sounds higher-pitched (possible throat irritation from salt), or if he stops his usual perimeter checks (neurological salt effects). Time his breathing—over 30 breaths/minute at rest signals distress.
Have a carrier ready. Small dogs crash faster than large ones when electrolytes imbalance. If his gums turn from pale pink to grayish, or if he can't settle in any position, bypass home care and head to the vet. Bring the hot dog packaging—the ingredient list helps calculate treatment.
