I think the vast majority of people dont leave them long enough before using them , personally i would get one done in the late summer so it gives the animal plenty of time to fire blanks the following year
I had 2 really big ones a few yrs ago there tails were really long as well not sure how big exactly but i struggled to get my hands round them at one point
The black bits in the coat could be flea dirt , get a damp peice of kitchen paper & comb some of the dirt from the coat onto the damp paper fold it over & if its got a red/brown halo round the dirt , then its fleas , treat accordingly
superb lovely & fattening
Sod that, it's toffee or feck all for me!
Have you had that popcorn thats got a sort if icing sugar on it , thats nice as well
14 weeks is very young still perhaps limit it to traffic one day & other dogs another day , maybe flooding the pup with all this new stuff's just to much for it in one go
