king charles cav pregnant

Question
I was just wondering if you would know an average of how many days a cav will be pregnant before she goes into labour it is her first litter she is 53 days today I know 63 is the average but do cavs usually have them earlier than this she is uite big and a bit off her food today are there any other signs to look for apart from temperature

Answer
Most dogs regardless of breed whelp around 63 days.
Take her temp twice a day at the same time every day. When it drops below 101 and stays there you will likely have pups within 24 hours. Also watch for nesting behavior, shredding newspaper etc.
Panting and discomfort.
Good luck
