We have a 9-week old Golden Retriever. She sleeps in a crate next to our bed and is a gem: quiet, doesn't soil or pee. When we leave her alone (for only 2 hours maximum at this point), she has been consistently pooping/soiling her crate. It seems like separation anxiety or perhaps some form of protest. She understands when she goes outside that she is to eliminate there and she does. She is very young and hasn't learned yet how to signal to go out so there are accidents, but we assume that will come. The crate pooping has us stumped. Could it be her food? Any help would be appreciated. Thanks.
