Hi we got a 10 weeks retriever home. She was 3.6kg at that time. Now she is 12 weeks old and weighs 4.9kg. While her weight has increased she is still below the weight guide on internet. Overall she is playful and has good appetite. We also struggling with her habit of eating poop. Both me and my wife take turns to be with her all the time so we can remove the poop as soon as she is done. We are wondering if she has worms or other digestion issues cause of which she is under weight. Her poop quality looks okay and she poops 3-4 times a day. We feed her 3 meals a day plus treats = 2 cups. We gave her a deworming tablet 1 week ago post which she has gained some weight. We are also thinking of giving her the deworming tablet again.
