their teeth and gums are fine (i clean Ebby's constantly as she has a bad bite, hence why she got placed in a pet home as she was sposed to be the breeders show dog) i check their mouths regularly anyway.
the smell didnt go so i took them to the vets and they had a minor tummy bug (baterial) which cleared up with a dose of AB's and their breath came good! they put it down to the pipe run off from our sink and we now have a sturdy cage (with a lid of course) around the outlet 🙂 as they both had it
p.s. i thought it was just me but i kept asking my partner and he said he could smell it too lol
