Fig. 1 shows an overlay of spectra obtained for NBR containing carbon in amounts ranging from 1 to 50 wt% using a diamond prism (refractive index, n = 2.4). From the bottom of Fig. 1, the respective amounts of carbon are 1, 3, 5, 10, 16, 20, 30, 40, and 50 wt%. WebSigns of dehydration include lethargy (not wanting to move around or play), thick saliva, sunken eyes, panting and a dry nose. Below we have listed some of the ways you can check at home if your dog is dehydrated. Of course, your veterinarian is the best person to determine if your dog is dehydrated, so when in doubt, check with them.
