When bathing a dog, what is the correct water temperature range to avoid thermal shock or discomfort?

• A. Ice cold
• B. Hot tap
• C. Lukewarm water, approximately 37-38°C
• D. Boiling

Answer: (C)

Water temperature for bathing a dog should be close to its body temperature—lukewarm, about 37–38°C—to avoid thermal shock and discomfort. This gentle range feels comfortable on the skin, helps the dog relax, and prevents rapid temperature shifts that can cause stress or agitation. Water that’s too cold can make the dog shiver and tense up, hindering the grooming process. Water that’s too hot can burn or irritate the skin. Boiling water is dangerous and must be avoided. A quick test is to feel the water on the inner wrist; it should be warm, not hot. If in doubt, start cooler and adjust gradually.
