check out my thread from this morning. it's worth it to invest in the CC systems, because I bought that other crap it it made Chewy look awful
Hope your pup is doing well and I wouldn't give too many baths at this age, they get very cold and nervous. Chewy is 5 months next week and he just got his first proper full soaked bath yesterday! It is a good idea however to keep their potty areas clean and give a little wipedown occasionaly with babywipes.
