Scout is a 5 year old Staffie x Boxer. He has a long history of shoulder issues and his shoulder was constantly inflamed and vet thinks has DJD.
He was struggling to walk 20 mins before and not enjoying walks at all. He went onto Previcox and Yumove advance and the change was amazing
He has always been good with other dogs there’ been the odd one or he doesn’ like big dominant dogs when he on the lead and always happy to be called away if we don’t like the look of a dog and he would ignore them.
He has started to become reactive to some other dogs yet still good as gold with others. Three times recently he has charged over to other dogs .. he is just full of bluster gets within 6 ft and stops and comes back. Obvs not acceptable I know. He has done it as well to dogs he knows esp if dusk or dawn and they suddenly appear..he gets there and then can see realised it’ his friend and gets all happy. Also he has become reactive on lead on our street walks which we had to do alot if when he was poorly. Think it started with all the cats that used to ambush us then progressed to anything that moved and sonmetimes things that dont move .. he has cicked off at a bag of rubbish before ..they just seem to get into a high alert in these walks times and I don’t enjoy them at all but sometimes a necessary evil.
Anyway he is on lockdown atm but wondered if the Previcox can cause any behaviour changes or maybe it’s a behaviour issue that’ been building up but he felt too poorly before to be bothered.. now he feels ok he reacts. I don’t think he is in pain …
Previously we could take him anywhere and he is ok most of the time. I do have a behaviourist that we did scent work with whi will chst tok as well but just wanted to see if you thought the Previcox might have any impact here in escalating aggressive behaviour/ enabling him to want to act on is feelings or if had seen anything similar
After having a bad week last week he has been brilliant over the weekend he has been ambushed by dogs and had all sorts of dogs come over to him and he’s been the perfect gent. Iv’e kept him under close control mind and will continue to do so.
One of the dogs he had a run at is very nervous and wonder if gives off some vibe dogs don’ like as I found out a friends dog had a go at this dog as well.
One of the dogs was running too and think he doesn’ like dogs running attached to people.. was on a canal tow path so narrow and they were upon us quickly before I could grab him. Still it is unlike him to react in such a way he is generally very placid.
I shall be keeping a close eye on him and thinking for him mind and avoiding anyone who might cause him worry .. def something about being worse at dawn and dusk .. I’m trying to work out a pattern.
I’ve never come across aggression as a side effect of previcox but it can certainly be seen in some dogs with OA.
It may be that as the previcox has made him more keen to walk his joints perhaps ache a little more after or during exercise now which can make them feel very grumpy and become aggressive to warn off other dogs as a way of protecting themselves. Arthritis is progressive so perhaps he needs some additional pain relief??
It may be that he is struggling a bit with his sight too, especially with you saying he is reactive to dogs at dawn and dusk so when light levels are not as good.
I would get him checked over by your vet and consider speaking with a behaviourist as Pollyanna has said.
It may also be worth getting a yellow lead/harness/collar as a signal to other dog owners that he isn’t too dog friendly while you try to get this sorted.
He has not been perfect in the past but if ever he took a dislike to something incidents were few and far between.. these things creep up on you there was the odd dog he didn’t like but often after chatting to other owners there are dogs their dogs dont like. He would sometime bark once and bounce away from dogs how noticed this started this charging is a new thing .. these things creep up on you used to be able to walk through the park not worrying who came along now I’ve no idea what will trigger it.. we have been ambushed by dogs before and he has been the perfect gentleman relaxed body language
Will mention to vets .. rimadyl didn’ work before and before he went onto Previcox he had a much worse quality of life . My vets was amazed at the difference in his demeanour alone on the meds
I would definitely speak to your behaviourist, especially if they are familiar with Scout. However, I would also speak to your vet. Whilst I have never seen it myself as a vet, Previcox has been associated rarely with nervous system disorders. Your vet would probably have to speak to the manufacturers to get more information as it is not a common side effect, but if behaviour change has been reported then it might be worth considering another NSAID.
