Bella (nearly 5yrs) hardly ever gies to the groomers as shes gotten older I take every 4-6 months but that's mainly for a good scrub, while she's there she gets her ears trimmed mainly the bit behind the ears. Her legs and paws done, these get cut fairy short. Her tail trimmed as when longish the fur dangles in poo when she does one. And her bottom area gets trimmed.
Apart from a few whispy bits that's it, the fur on her body has never required cutting.
Mollys 10 months and not had anything done yet
