How much to bottle feed my 3-week-old Rottweiler with watery poop?

Updated on September 23rd, 2025

Pet's info: Dog | Rottweiler | Female | unspayed | 26 days old | 2.5 lbs

I have a 3 week old Rottweiler who is about 2.5 lbs. I just want to make sure I am bottle feeding her the correct amounts and as often as I should. Ive tried by calculation Ive seen online, but I dont think my math is correct. How much do you recommend feeding her per feeding and how often for her weight and breed (I attached what formula instructs)? Also, how much should she poop? She poops once a day and its started to be really watery. and she is still very active and playful.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach!

Since you are bottle feeding I would start to wean sooner than if she was nursing from her mom. Milk replacers tend to either constipate or cause diarrhea. Since she is having loose stools I would have a fecal tested at the vet for parasites. Coccidia is common in puppies. By 2 weeks of age you can start dewormning with pyrantel pamoate every 2 weeks. Starting at 4-5 weeks offer canned puppy food and milk replacer twice daily. At 5-6 weeks mix canned with dry puppy food and bottle feed once daily and by 6-7 weeks just dry and off the bottle by then.

Once stool a day is not enough. I would buy a different brand of milk replacer and mix with what you are using now to get a better consistency for the stool.

2.5 lbs=40 ounces, so you should be feeding 50 mls every 3-4 hours or 350 mls per day. I would divide that out every 4-6 hours and see how things go and start weaning in the next 1-2 weeks.

I hope this helps!
