Please don't feel like a bad mom -- you were a good beagle mom for taking Charlee to the vet!If Charlee doesn't mind being bathed (and you can always make it a fun time with treats), you might try a nice, soothing oatmeal shampoo and then use the cream rinse from the vet. If his paw didn't swell up, it might have just been an ant bite. If he still seems to be bothered by it, you can hold a warm, wet compress/cloth on his paw to quiet it down. One thought about the car -- be sure to take Charlee for short rides that end up at good places so he doesn't always associate the car with going to the vet. Charlee is going to get into so many more adventures as he grows up -- you've only just begun!
