Ari is a sweet sensitive boy. He appears to be house trained. He''s been tolerant with other dogs. So far he''s just been a gentle, fun little dog. HEALTH: Ari tested positive for heartworm and is being treated by Fairfax Animal Hospital. He has had treatment and is in recovery. The slow-kill heartworm treatment used for Ari will require him to return to the vet for a follow up heartworm test around 5/10; in the interim Ari must have monthly heartworm preventative. Adopter will be responsible financially for heartworm test in May (approximately $50) and any additional treatments(if needed).
