I have a 6 years old bull. A few month ago, he started loosing weight. After check up by vet, he received antibiotics because his blood was too thin after being stunt by an insect...... after the antibiotics, he stopped loosing weight for a while, but now id loosing again (he is eating a lot of food) he is also loosing hairs and has diarrhea. If someone can help me..... Thank you
