Why size and gestation stage matter here
At 6 kg, your Corgi is small enough that a teaspoon of soy sauce delivers a substantial sodium hit — roughly a third of her maximum safe daily amount in one lick. Pregnancy increases her fluid needs, so her body has less reserve to dilute the salt. First trimester puppies are less affected than late-term ones, but maternal stability is always key.
If this happened in her last three weeks of pregnancy, the risk increases as her blood volume peaks. Watch closely for nesting behaviors that seem off, like excessive panting between contractions if she's near term.
The subtle signs owners often miss
Before obvious vomiting or diarrhea, you might notice her licking the floor obsessively or pawing at her mouth — early salt irritation. Pregnant dogs sometimes mask discomfort, so check her gums; if they're tacky instead of slick, she's already dehydrating despite drinking.
Listen for stomach gurgles louder than normal pregnancy noises. Time her breathing when resting — over 40 breaths per minute warrants a vet check, as salt can cause fluid shifts in the lungs.
How to support her system right now
Offer ice cubes or wet her regular food with low-sodium broth to encourage gradual rehydration. Sudden large water intake could trigger vomiting, making electrolyte issues worse. Keep her in a cool area — salt toxicity raises body temperature, which is extra risky during pregnancy.
If she's due for prenatal vitamins, check with your vet before giving them — some contain minerals that could interact with the salt load. Skip any scheduled training treats today to avoid adding more sodium to her system.
When to call even if she seems fine
Any reduction in puppy movement over the next 48 hours needs vet assessment — salt can cause temporary decreases that should be monitored. Likewise, if her urine output drops after an initial increase, it suggests her kidneys are struggling.
Note her resting heart rate now for comparison; over 120 bpm in a relaxed pregnant dog could indicate circulatory stress. Save packaging from the soy sauce in case the vet needs to check added ingredients like garlic or onion powder that sometimes appear in specialty brands.
