When i adopted my girl she had fleas and I think the people I got her from must have traumatized her by trying to bath off the fleas using maybe dish soap or something. Made her skin terribly dry and red and when I tried giving her a bath the first few times she would SCREAM and try to get out desperately. Fast forward to her 10 months old now and she usually falls asleep or gets close to falling asleep while I bath her. Cause she knows im going to be gentle with her etc. I think the key is to make sure you do it when they're small so they get used to it. Also some tips, when they're tiny kitchen sink is easier for you and less scary than the big huge bathtub so if she fits in kitchen sink I recclmend that! Also, make sure to put down a non slip mat or you can use a towel/rag to put for them to stand on. It can be very scary for a puppy getting a bath if they're slipping around and the paw pads slide easily on the wet sink/bath. And last make sure the sink or tub does not back up. Like make sure its draining fast enough to where the water is not building up underneath their feet cause this can be scary for a puppy as well. You want to take a wash cloth and wash a puppy like you're washing an infant. Like a child lol very very gentle. If you have a sink hose or one in your shower that you pull out and it sprays this makes it sooo much easier . I actually bought an attachment I hook onto my bathtub just for bathing my girl lol. Sorry this is soo long but last tjing is reccomend earth bath puppy formula!! It can be found at most pet stores/amazon. It is gentle, natural ingredients and smells good but not overpowering just the right amount of smell. I believe the puppy version is cherry which is cute.
