The good news is, he is physically healthy now. But due to his past trauma, he has become aggressive and needs behavior modification and bit one of the family members. However, family members do not want to leave him at all but need the money to pay for his board and train with a Behavior Expert. If not treated, no family will be able to keep him due to his biting nature.
No amount is big or small. Pluto will forever be grateful to you all.
