A.T.
My cat did this and he had crystals in his urine. The vet gave him meds as well as changing the food. He is now on $17 a bag food! I would definately take the dog to the vet- either the same one or a new one. There may also be a some jealousy if the dog can sense you are pregnant. If she is spoiled, have you not been spoiling her? If your behavior towards her has changed, that would be a signal to the dog as well. I would definately mention all this behavior "stuff" to the vet being tied into your pregnancy. Just remember, some vets are better than others just like in any profession. So get a second opinion if necessary.
