My kitten has been listless, not eating or drinking for two days, with abnormal stool and always sleeping, weak when it reacts

Not eating and lethargy are signs of illness needing a vet exam; with diarrhea, vomiting, or fever, an unvaccinated kitten may have distemper, and an undewormed one may have internal parasites; FIP, hepatitis, nephritis, or constipation also show this. See a vet.

My dog had a worm like in the picture before topical deworming; now many dead worms are in its bed and live ones on its tail/hind legs; it eats less and has slight hair loss on head/tail but is still activeโ€”what’s wrong?

Per the image, the dog has a tapeworm infection. The worms come from the anus; tapeworms are internal parasites needing oral dewormer. Worms pass the same or next day; re-deworm in 2 weeks to remove eggs. Regular internal and external deworming prevents recurrence.

Why does my German Shepherd often have diarrhea?

A German Shepherd's frequent diarrhea can be caused by many factors. First, improper diet is a common cause - the dog may have eaten unsuitable or contaminated food. Second, problems with the digestive system can also lead to diarrhea. In addition, internal parasite infection can cause frequent loose stools, and allergies, intestinal infections, stress, and anxiety can also trigger diarrhea. If the diarrhea persists or other uncomfortable symptoms appear, take the dog to a vet. To prevent diarrhea, keep the diet appropriate, maintain a clean environment, and deworm regularly.

There are white wriggling things under my dog’s rear. I dewormed it yesterday but they’re still there today, and now I’m afraid to give more dewormer. What should I do?!

Based on your description, it is normal for your dog to still be passing worms the day after deworming. When a dog infected with internal parasites takes a deworming medication, it will gradually expel eggs and worm bodies in its stool, usually clearing them within 3-7 days. If worms are still being passed a week after treatment, or if large numbers of eggs or worms appear, the infection is more serious and a second round of deworming is needed.

My dog keeps coughing and gagging with yellow foam and a little bloody stool

Persistent cough, gagging, yellow vomit and bloody stool may be: 1) a swallowed sharp foreign body causing gut damage and bloodโ€”needs X-ray and surgery; 2) canine parvovirus or coronavirus, with bloody tomato-like stool, vomiting, dehydration, low spiritsโ€”needs a vet; 3) internal parasites with gut inflammationโ€”needs deworming. The first case seems most likely; see a vet.

Why does my koi get thinner as it grows?

A koi getting thinner may have many internal parasites draining its nutrition and hurting appetite. Bacterial infection or gut problems also cut intake and cause steady thinning. Take it seriously and help promptly.

My cat’s stool has no worms, but white rice-like tapeworm segments often stick to its rear; I dewormed inside and out once in the morning, worms stopped, but by evening they appeared again

Tapeworms are internal parasites needing cat-specific oral dewormers (fenbendazole, etc.); they shed white rice-like egg segments and are stubborn. After deworming, if segments reappear, re-dose, then deworm again in two weeks to clear them. Deworm monthly and avoid raw water, dirty water, and raw meat.

Why does my dog lose weight rapidly?

Rapid weight loss may come from digestive disease, gut infection, internal parasites, or thyroid problems, all lowering appetite. If it keeps losing weight, see a vet to find the cause. Roundworms, hookworms, and other parasites also cause gradual thinning, needing deworming.

My cat has soft stools with mucus but normal spirits after vaccines and deworming; should I see a vet?

Soft stool with good spirits usually rules out acute infectious disease; it is likely diet, gut flora imbalance, or internal parasites. Overfeeding, irregular meals, or an intolerant food causes it; fast half a day, give probiotics, then small frequent easily digested meals. If it recurs, get a fecal test, deworming does not cover coccidia or tritrichomonas.

My cat has soft stools, meows for no reason, and sleeps all day. Is something wrong?

Soft stools in cats have many causes: poor digestion, parasites, or spoiled food. A recent food change can upset the gut, and probiotics plus a gradual transition help. Internal parasites such as tritrichomonas, coccidia, or giardia also cause soft stools and need deworming.
