Gracie Ruth slept more during her teething. She also whined a lot. She really seemed to be in a lot of discomfort. I'd freeze wet wash clothes for her to chew on. I also would put her favorite plushie toy, Duckie, in the freezer for awhile to make it colder. She'd just walk slowly through the house with Duckie in her mouth making the most pitiful little cries. It just broke my heart to see her like that. I also cracked her kibble so that it was easier for her to eat. Although they ate the same type of food, Boo thought she was getting something special to eat, so I'd crack some for him too.
Now Yogi, the only sign I had that he was teething was that his ears drooped at times. He never seemed to slow down and he certainly didn't need his kibble cracked.
