Your dog has no way to tell you her throat feels funny, nor does she have much recourse other than to try drinking it away. Diarrhea and vomiting can deplete your dog's fluids, making her excessively thirsty. If you suspect an allergy or intolerance, your vet can design an exclusion diet to figure things out.

Lettuce spread to the Greeks and Romans, the latter of whom gave it the name  lactuca , from which the English lettuce is ultimately derived.By 50 AD, multiple types were described, and lettuce appeared often in medieval writings, including several herbals.ettuce's native range spreads from the Mediterranean to Siberia, although it has been transported to almost all areas of the world. Plants generally have a height and spread of 6 to 12 inches (15 to 30 cm). The leaves are colorful, mainly in the green and red color spectrums, with some variegated varieties.
With leafy lettuce greens like romaine, red leaf or green leaf lettuce, you can follow the same process. I have found though that it is better to remove leafy greens from their plastic bag and pat the leaves dry with a paper towel before storing them if they are wet from the produce sprayer at the store.
