My 4 month old pekepoo stuck his face in my large mug of hot Starbucks Sumatra coffee with skim milk.Then, he sneezed and spit the coffee all over the leather sofa and threw up on the carpet. Does the coffee and pekepoo spit have a long term detrimental effect on the sofa, even if I wipe it up?The sofa also faces similar assaults on occasion from his wet feet. I try to keep him off it but sometimes he is too fast for me. If I wipe up the moisture, is it still bad for the sofa and is there anything I should treat the sofa with to make it less likely this will harm it in the long term?
Wipe down the sofa with warm water on a soft rag. Consider washing it with saddle soap. I have only used it on shoes, handbags and boots, so no idea how long this will take. You can find it with shoe police at your local store. Or there may be some type of leather treatment cream that will restore the look of your sofa. As for the dog, consider getting a blanket that stretches all the way across the seat of the sofa, fold it in half lengthwise, and insert long pieces of aluminum foil between the layers. Put this on the sofa. Dogs and cats hate it and will avoid the sofa. It will protect the sofa when you cannot. Be sure to tuck it in firmly around the edges when you are not at home. (It will look fine if you choose a blanket that goes with the decor; try it first with something you have on hand.)
