Hours and intake
The current website says the facility is open 8 a.m.–11 p.m. daily, but separately says walk-ins and emergencies are accepted during DVM hours of 10 a.m.–11 p.m. Call before traveling, especially before 10 a.m.
Care offered
The site describes urgent/emergency care for dogs and cats plus surgery, diagnostics, ultrasound, dentistry, dermatology, wellness care and other services. Some patients may need referral or continuous care elsewhere after stabilization.
Conflicting public information
Older official East Valley Emergency Pet Clinic PDFs still advertise a former overnight/weekend schedule. Current referral pages also disagree on phone number, with some publishing 909-895-0150. Help My Pet is asking the clinic to confirm which information is current.
Costs and practical support
A current Scratchpay partner directory lists the clinic. Ask directly about deposits, estimates and payment/financing options. For broader next-step help, see payment, assistance and fundraising resources.
