I have a leather slip collar with lead attached. Is this appropriate for a 6 month old puppy or do I need a chain one?
What does your dog do best on? That's your answer. I think many people default to "this is what the breed shows in...use it!" when that's not always what's best for the DOG.
I like to start my puppies on a slightly wider nylon choke that's not so hard on their throats, and get them used to the sensation of a collar up behind their ears without cold metal making the experience worse than it might be for some.
If the show is Friday is it ok to bathe and groom on Thursday? Will the oil in coat return that fast?
That's fine. I groom 1-2 days ahead of time. I've got a show this weekend, was going to bathe my bitch today, didn't work out. She's being bathed tomorrow and will be just fine for showing. Don't worry so much about the oil returning to the coat, that'll take care of itself.
A big reason for bathing beforehand is to open up the coat, check for any sores/rashes/parasites (ticks are nasty bastards), and give them a good groom through to make show day preparations either.
Tip to help hide a mild steep croup?
Back blow, back brush, hairspray/holding mousse, sculpt into place.
What are the essentials I need to bring?
Forced Air Dryer
Any Coat Conditioners or Sprays
Plastic Bags/Pooper Scooper
Mild bleach solution
