i can usually tell a rough coat at birth ,,,,,,,,,,,,,but the broken coat can sometimes be more difficult ,as this litter could be all 3 coat types lol
i have a couple of toads in the garden, one of the dogs has tried to eat them ,and just having 1 in there mouth made them look like they had rabies ,frothing from the mouth and really uncomfortable ,drooling everywhere ewwwww
ears quite often fly around when the pups are teething ,if its really bothering you you could try what fox terrier people do ,they copydex the ear down for a few weeks
i agree with previous thread about vitalin ,my mate uses jameswellbeloved on her bedlingtons ,due to them being itchy,and i find evening primrose usefull as well, you could always strip him ,take out the dry coat
