I have a shihtzu who is nearly 8 years old. Occasionally when she has been bathed she starts to gasp and seems to be struggling for breath. This lasts about thirty seconds, I just speak calmly to her and she stops. This doesn’t seem to happen at the groomers, I wondered if it was a claustrophobic thing when she’s done in the shower but have just bathed her outside and she’s done it again. The vet says her heart is fine so I don’t know what it is. Anyone else had this
