In December, Luna started having some gasping panic attacks. I started her on twice a day albuterol treatments and the panic attacks have stopped, as has most of her wheezing. Luna loves to sit and have her head scratched, and has come to be pretty accepting of the breathing treatments. I think she knows they help her. To do the breathing treatments you need to have a nebulizer machine, tubing and a nebulizer set up.
Used machines are frequently available at much lower prices.
Another option would be to get a group together to split the cost of the machine. You may need a prescription to get a nebulizer. When I was calling around checking prices, some places said I did need a prescription and some said I didn t, so you will need to ask. The suppliers that said I needed a prescription said they would be happy to accept one from my vet. The equipment is available in medical supply stores and some pharmacies.
