Pet advice

Help. We have a 2 1/2 year old guy, his name is Jake. He used to have another big friend, but unfortunately he got hit by a car about a month or two ago. Jake has been our only dog since then, getting absolutely all of our attention 24/7. Last week, he was attacked inside our home by a stray dog and has been very protective of me, still scared himself, and doesn’t want to leave my side.

We’ve been searching for a dachshund for about 8 months and finally found one. He’s older, 10-12. He’s only ever lived in the same home with the same owner, until he passed away about 3 months ago. We haven’t even had new pup for 24 hours but Jake is extremely 210% jealous. It’s absolutely breaking my heart into pieces. I just want to cry (that might be pregnancy hormones here at almost 21 weeks).

How long of an adjustment period do we give? I don’t want Jake thinking we replaced him. 💔💔💔
