Puppy (7 months) was shaking before going into puppy day care. She's been about 5 times, just for a morning each time.
They said she loves the walk bit, is fine with the other dogs, but seems anxious just before lunchtime before we come and pick her up.
They've suggested she might be better if she did 2 sessions a week rather than one, or stayed for the whole day. They mostly nap in the afternoons.
We are sending her partly for socialisation, she's good with other dogs, but also so it's not a shock for her if she has to go in for some reason, and also as we have cleaners in the morning she goes so its easier if she's not there.
