Veterinary questions? Ask a Vet for Answers ASAP
Hi, Welcome to Just Answer. I'm Chris, a small animal Vet based in the UK. I am reviewing your question and will get back to you as soon as possible
Can I ask how far into her pregnancy she is? Also what was the reason for giving those medications to her?
I wouldn't worry so much about the green lipped muscle, but the cod liver oil I would not recommend to give to dogs due to the risk of toxicity from high levels of vitamin A and D.
I would discontinue both of these supplements whilst your dog is pregnant and feeding the pups.
I would also recommend an ultrasound scan at around 30 days to check that the pups are appearing normal and healthy.
The risk should be small as it is generally with long term use that we seem to see problems, unfortunately there is no way to know if there has been any affect on the foetuses at this stage.
