What does the package recommend for how much to feed? I usually use that as a gauge.
I know some members have a professional dog grooming table. But, if yours is a pet, it's not really necessary - unless you really want one. Grooming takes time for you and your puppy to adjust to. Comb him regularly and before you know if, he'll stand still for you. Puppies have a tendency to not stand still. It's pawfectly normal.
Just use one hand to hold him and the other to brush. Just make sure you're careful in the leg areas as they're more sensitive there.
I highly recommend doing a first vet check up. When I got my two, I took them to the vet for a routine check within 2 weeks of bringing them home. You (or your family) may not feel like it's necessary, but the first visit is usually recommended.
