Multiple dog walking???

I have 5 dogs so my sims every other day spend a good amout of time taking the dogs for a jog which at this time is the quickest to get through them. I had 2 dogs, adopted 2 strays only to find out one of them were pregnant. I have no mods in my game. It became too tedious making sure they were kept up to date so once sims 4 came out, I didn't bother. LOL
