Soft poop

Hi can any one help me my puppy poopy is 11 weeks old tomorrow and over the weekend we tried to introduce a new food and the first day she poop for England so we stop adding the new food because we fort it was to rich for her. Since then her poops have been very soft. Some times they are hard then soft the rest of the time she has been pooping about five times a day. She is on dry food and a very happy puppy doing the normal puppy things barking at cats playing and trying to eating hubby's laces. 
Just worried that her poops won't harden. 
Sorry for long message 
Sue and poppy x 

If you are changing food it is best to slowly add in the new food so it won't upset their stomach. Just add a little more of the new food every day for 5-7 days.

Yeah if you do it gradually should be ok   

What are you feeding? x

I've just read on here something about changing her diet to fish as chicken might not agree with her I have stoped feeding her wet food after reading on here how rubbish it was x

Yes I changed to fish, what are you feeding?

It's called vets kitchen I got some food from the vets called science plan vet essentials that's what I tried to add to her old food

Hubby is working nights have sent him a text telling him to go puppy food shopping in the morning lol x

As a pup I would refrain from swapping and changing food x

So would u recommend keeping her on the chicken and rice and slowly change to the fish or just keep her on the chicken x

Was here a reason why you wanted to change?

Just to update poop all ok now she had her 12 week injection yesterday told the vet about it and he said it was normal in some pups so food is just to rich for them

Glad she's OK x
